ACPI: autoload modules - Create ACPI alias interface
Modify modpost (file2alias.c) to add acpi*:XYZ0001: alias in modules.alias like: grep acpi /lib/modules/2.6.22-rc4-default/modules.alias alias acpi*:SNY5001:* sony_laptop alias acpi*:SNY6001:* sony_laptop for e.g. the sony_laptop module. This module matches against all ACPI devices with a HID or CID of SNY5001 or SNY6001 Export an uevent and modalias sysfs file containing the string: [MODALIAS=]acpi:PNP0C0C: additional CIDs are concatenated at the end.
