As a data point, the test case works fine for me with git Xorg as
of 2008-04-01, with the patches from bug 15333 and bug 15345 applied
on an ATI rv350 using EXA.
(From the age of the bug I suspect that those EXA-specific patches
aren't relevant to the original bug report, though they do cause misrendering of
cairo gradients.)
