This may be related to white line we see with 3d acceleration.
The fix is to program some memory config register. But for
time being i don't think anypatch have been provided for xorg.

Maybe for fixing the lockup of radeon 9800 we will have to
add some setup in xorg driver and thus program this register
that will likely fix this things you seing.

Btw i don't think a kernel 2.6.12 could fix this but with
strange interaction it could...
