That depends on how Windows 8 works. If Windows 8 policy is handled by
the GPU drivers then it belongs in i915. If it's handled by the

According to Matthew Garrett, Windows 8 leaves backlight control up
to individual graphics drivers rather than making ACPI calls itself.
There's plenty of evidence to suggest that the Intel driver for
Windows [8] doesn't use the ACPI interface, including the fact that
it's broken on a bunch of

First of all, there is a bunch of boxes where ACPI backlight works incorrectly
