It looks like i915 is in control of the backlight. Either it was designed this
way, or there's an additional mux that needs switching for backlight, or
something else... I don't really know.
Reassigning to non-Intel, maybe the Radeon folks have more clues?

The radeon driver should add a backlight control if the platform utilizes the
GPU's backlight controller. If there is no radeon backlight interface, the
platform uses some OEM specific backlight control (probably Intel or ACPI). I
suspect you will have to use the intel backlight control to control the
backlight.

Is there any way to trace ACPI calls and Intel card state (enabled or not)
on Windows? It works there, so maybe I can get some information.
