Possible a known limitation of radeonhd:

from
http://www.x.org/wiki/radeonhd#head-d0cfd39d1b149a43f0c1d862f21f4b3ddcb43ae2

"Panel brightness cannot be changed because ACPI events aren't handled
properly. Workaround: Switch to a different virtual terminal for that. Affects
backlight on a number of laptops, e.g. from the IBM/Lenovo ThinkPad series.
(Seems to be fixed in git since some time in 2008-03, needs to be verified)"

My hp Conpaq 8510p has Radeon Mobility HD 2600 and no brightness contol, even
when I disable the environmental sensor in the BIOS.

BTW, after running OpenSUSE 11.0 b3 once, brightness control also failed in
Windows XP on the same machine.
