--- Comment #4 from Alex Deucher <alexdeucher at gmail.com> ---
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.
