FWIW, my glxgears says:
The framerate should beapproximately 1/1835103081 the monitor refresh rate.
It then runs fine. I'm on radeon r200, but since my update yesterday
(git master stack using gentoo overlay) I also have OpenGL problems,
most notably, KWin 4.4's compositing doesn't work any more. Probably,
this isn't just intel then.
My old X did work fine, dating from when the DRI2 Swapbuffers lifetime
bugfix hit master (711e26466ae04ae93ff4c48d377d83d68a6320e9).
If it helps, I can provide anything that doesn't take me a whole day to
