Well...you -are- running drivers from git.  Breakage happens as a normal part 
of development...it's just sort of unavoidable sometimes.   But that's why 
we're helping testing it, right?

That's weird...fullscreen 3D is working fine for me.  I'm running xserver 
1.7.5, xf86-video-intel master, mesa master, libdrm master, dri2proto master, 
and the for-linus kernel.

Compositing in KWin seems broken for me, but it at least doesn't stall...I'll 
try and track that one down.

Good luck.
