This patch fixes build failure of v3.9-rc5. When config ACPI_VIDEO as m, DRM_GMA500 as y, here comes the failure. gma5/600 needs acpi_video just like nouveau.
Failure message: drivers/built-in.o: In function `psb_driver_load': kernel-3.9-rc5/drivers/gpu/drm/gma500/psb_drv.c:340: \ undefined reference to `acpi_video_register' make: *** [vmlinux] Error 1

Hi
Thanks for catching this, but if I can be picky, I'd prefer if you wrote it like i915 does. E.g.
select ACPI_VIDEO if ACPI select BACKLIGHT_CLASS_DEVICE if ACPI ...
And you can skip X86 since we already 'depend' on it.
Thanks Patrik
