Linux-2.6.12-rc2
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

+ ---help---
+ Advanced Configuration and Power Interface (ACPI) support for
+ Linux requires an ACPI compliant platform (hardware/firmware),
+ and assumes the presence of OS-directed configuration and power
+ management (OSPM) software. This option will enlarge your
+ kernel by about 70K.
+
+ Linux ACPI provides a robust functional replacement for several
+ legacy configuration and power management interfaces, including
+ the Plug-and-Play BIOS specification (PnP BIOS), the
+ MultiProcessor Specification (MPS), and the Advanced Power
+ Management (APM) specification. If both ACPI and APM support
+ are configured, whichever is loaded first shall be used.
+
+ The ACPI SourceForge project contains the latest source code,
+ documentation, tools, mailing list subscription, and other
+ information. This project is available at:
+ <http://sourceforge.net/projects/acpi>
+
+ Linux support for ACPI is based on Intel Corporation's ACPI
+ Component Architecture (ACPI CA). For more information see:
+ <http://developer.intel.com/technology/iapc/acpi>
+
+ ACPI is an open industry specification co-developed by Compaq,
+ Intel, Microsoft, Phoenix, and Toshiba. The specification is
+ available at:
+ <http://www.acpi.info>

+ depends on EXPERIMENTAL && PM
+ default y
+ ---help---
+ This option adds support for ACPI suspend states.
+
+ With this option, you will be able to put the system "to sleep".
+ Sleep states are low power states for the system and devices. All
+ of the system operating state is saved to either memory or disk
+ (depending on the state), to allow the system to resume operation
+ quickly at your request.
+
+ Although this option sounds really nifty, barely any of the device
+ drivers have been converted to the new driver model and hence few
+ have proper power management support.
+
+ This option is not recommended for anyone except those doing driver
+ power management development.

+ help
+ This driver registers for events based on buttons, such as the
+ power, sleep, and lid switch. In the future, a daemon will read
+ /proc/acpi/event and perform user-defined actions such as shutting
+ down the system. Until then, you can cat it, and see output when

+config ACPI_ASUS
+ tristate "ASUS/Medion Laptop Extras"
+ depends on X86
+ default m
+ ---help---
+ This driver provides support for extra features of ACPI-compatible
+ ASUS laptops. As some of Medion laptops are made by ASUS, it may also
+ support some Medion laptops (such as 9675 for example). It makes all
+ the extra buttons generate standard ACPI events that go through
+ /proc/acpi/events, and (on some models) adds support for changing the
+ display brightness and output, switching the LCD backlight on and off,
+ and most importantly, allows you to blink those fancy LEDs intended
+ for reporting mail and wireless status.
+
+ Note: display switching code is currently considered EXPERIMENTAL,
+ toying with these values may even lock your machine.
+
+ All settings are changed via /proc/acpi/asus directory entries. Owner
+ and group for these entries can be set with asus_uid and asus_gid
+ parameters.
+
+ More information and a userspace daemon for handling the extra buttons
+ at <http://sourceforge.net/projects/acpi4asus/>.
+
+ If you have an ACPI-compatible ASUS laptop, say Y or M here. This
+ driver is still under development, so if your laptop is unsupported or
+ something works not quite as expected, please use the mailing list
+ available on the above page (acpi4asus-user@lists.sourceforge.net)

+config ACPI_TOSHIBA
+ tristate "Toshiba Laptop Extras"
+ depends on X86
+ default m
+ ---help---
+ This driver adds support for access to certain system settings
+ on "legacy free" Toshiba laptops. These laptops can be recognized by
+ their lack of a BIOS setup menu and APM support.
+
+ On these machines, all system configuration is handled through the
+ ACPI. This driver is required for access to controls not covered
+ by the general ACPI drivers, such as LCD brightness, video output,
+ etc.
+
+ This driver differs from the non-ACPI Toshiba laptop driver (located
+ under "Processor type and features") in several aspects.
+ Configuration is accessed by reading and writing text files in the
+ /proc tree instead of by program interface to /dev. Furthermore, no
+ power management functions are exposed, as those are handled by the
+ general ACPI drivers.
+
+ More information about this driver is available at
+ <http://memebeam.org/toys/ToshibaAcpiDriver>.
+
+ If you have a legacy free Toshiba laptop (such as the Libretto L1
+ series), say Y.

+ and firmware have support for hot-plugging physical memory. If

+ memory DIMMs at some platfrom defined granularity (individually
