i've disabled FB_RADEON_BACKLIGHT (FB_BACKLIGHT also got deselected)
and i managed to boot into 2.6.21-rc1 and have a working backlight.

i don't have my laptop with me but i am pretty sure
FB_RADEON_BACKLIGHT wasn't set for 2.6.20 (i think it showed up as a
new option when i did make

BIOS+ACPI, actually. Without ACPI video loaded, the firmware does
everything correctly. With ACPI video, the firmware does it, then its
changes are clobbered over by ACPI video's.

Dear Kernel Developers,
Since the most recent successful for me kernel 2.6.19-rc6-mm1, I've
tried few times to build more recent snapshots and now finally
2.6.20-mm2. In all those cases I have a sad outcome -- kernel boots but
