---help---
- Enables hot key handling over the input layer by default. If unset,
- the driver does not enable any hot key handling by default, and also
- starts up with a mostly empty keymap.

- If you are not sure, say Y here. Say N to retain the deprecated
- behavior of ibm-acpi, and thinkpad-acpi for kernels up to 2.6.21.
+ This option enables thinkpad-acpi hot key handling over the input
+ layer at driver load time. When it is unset, the driver does not
+ enable hot key handling by default, and also starts up with a mostly
+ empty keymap.
+
+ This option should be enabled if you have a new enough HAL or other
+ userspace support that properly handles the thinkpad-acpi event
+ device. It auto-tunes the hot key support to those reported by the
+ firmware and enables it automatically.
+
+ If unsure, say N here to retain the old behaviour of ibm-acpi, and
+ thinkpad-acpi up to kernel 2.6.21: userspace will have to enable and
+ set up the thinkpad-acpi hot key handling using the sysfs interace
+ after loading the driver.
