Yes I think I fixed it in
http://gitweb.freedesktop.org/?p=xorg-driver-xf86-video-ati;a=commit;h=85e2ee6de6fd347aad66785ec7119f92013cd994

which is in 6.6.1 for X.org 7.1.

I've just pushed a bunch of fixes to the X.org 7.0 compatible branch
of ATI (ati-1-0-branch) in git. with that fix in there. I'm not sure
I'll make a release from that branch but I could be persuaded if
enough 7.0 users ask.
