Not much we can do about broken graphics drivers.
Try filing a bug at http://ati.cchtml.com and crosslink the two bugs (i.e. put its url here, and put this bugs's url in a comment there).
THANKS Dan, at least now I know what to do. I filed this bug report: http://ati.cchtml.com/show_bug.cgi?id=1163
Let's hope they'll reply... or I'll have to sell my card and buy an nVidia one...
