If FB_RADEON_BACKLIGHT wasn't set for 2.6.20, can you try 2.6.21-rc1
with that option disabled?

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 oldconfig). i'll post the difference when i
get home tonight and also try disabling it.

Correct. You need to enable the backlight for the radeon card.

The problem is when that is set, the device doesn't work as they need
the ibm ACPI driver, not the raedon one.
