If you're looking for testers, I was just pointed to Michel's original
patch (http://lists.x.org/archives/xorg-devel/2011-March/020716.html) by
Mario Kleiner over on mesa-dev.  In initial testing, it appears to solve
a very nasty X crash when unlocking an OpenGL screensaver (and probably
when exiting any full-screen program) with KDE desktop effects enabled
on Intel GPUs.

Since I used to see the same corruption of the screensaver unlock
dialog on my ATI card, I suspect that it also fixes the KWin crash that
inevitably followed shortly thereafter.

I suspect that you can find a fair number of eager testers here:

If there's a different iteration of the patch that you would like me to
test, please point me to it.  Otherwise, I would urge you to get this
thing pushed.
