kernel/applesmc_update.patch
Matthew Garrett 0988eed04e - applesmc_update.patch: Make the driver more generic. Should help Apples. 
- apple_backlight.patch: Make sure that this loads on all hardware.
- efifb_update.patch: Fixes for the 11 inch Macbook Air
- acpi_reboot.patch: Should make reboot work better on most hardware
- efi_default_physical.patch: Some machines dislike EFI virtual mode
