I think the parameter "Does the ACPI backlight interface work or not" belongs to the ACPI video driver.
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 ACPI code then it belongs in the ACPI code.
I fail to see the logic. Windows 8 policy dictates whether we can use the AML code or not. IMHO, ACPI code is in the best position to figure this out and quirk as necessary. It's the part that knows about Windows 8, not i915.
So if nvidia hardware uses the ACPI interface and Intel doesn't, we should still quirk it in the ACPI driver?
