Hello all.
I mailed last summer about a crash with a ATI-card here:
http://marc.theaimsgroup.com/?l=open...3632715144&w=2

Jonathan Thornburg (jthorn@aei.mpg.de) also mailed about thr problem here:
http://marc.theaimsgroup.com/?l=open...3844021367&w=2

X.org has now finally fixed it.
All info can be found here:

I would be very very happy if somebody could commit the patch.
Thanks.
