Bug#433876: works for me too :-)
i am adding this remark for the sake of documentation only :-)
i filed a bug report a while back : 402584
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=402584
in which i thought that the brightness control special keys Fn7-Fn8 do not
work because of ACPI issues.
BUT... now that i found this bug report just a few minutes ago :-)
and followed its instructions to install experimental ati xorg drivers which
now solved this issue for me on Compaq Presario 1500 with Radeon Mobility M7
LW [Radeon Mobility 7500] i'll close and redirect the other bug report.
