You guys might want to try adding
http://git.kernel.org/?p=linux/kernel/git/airlied/drm-2.6.git;a=commit;h=96600602cd71892a470bb9e89302152d764d45a9
to the free driver,
not sure if it'll fix the backlight.

As for fglrx you might be able to extract the BIOS and shove it into
0xc000 location where fglrx will most likely look for it, though I'm
not sure how best to do that.
