Comment 562 for bug 359392

The bug has happened both ways, usually faster if one has Compiz. If you enable the proposed repo, you'll upgrade to a Compiz that doesn't have the X3100 on the blacklist. Be careful, though, as a new kernel somehow didn't get into proposed and you'll only be able to do a partial upgrade

Martin, in what capacity I've been able to test it (I'm "addicted" Xorg-edgers, but I tested a manual compile of it), the patch works beautifully.
