[PATCH] [Maverick] Add support for the ATIF ACPI method to the radeon driver

[Alberto Milone]

Hi all,

Thanks to the help of Alex Deucher and Matthew Garrett, I've added
support for calling the ATIF ACPI method to the radeon driver. This
makes the video switch hotkey work properly, as we get an ACPI event
when the key is pressed.

Note: I guess it depends on the bios I'm working with, but I also need
to pass acpi_osi=\"!Windows 2009\" on boot in order to get the ACPI
event.

The patch has been approved by upstream and should be included in
2.6.36. Please consider adopting my patch in Maverick's kernel.

Thanks,
