i see some corruption on a radeon hd 4670 card with konqueror menus, that
goes away with i disable radeondrm.  however, then the card performance
is absysmal there, and i have no Xvideo.

i bet this is the same problem.  it's on my list of things to deal with.

thanks for testing all these combinations and reporting the results.
