I had a strange issue last night. After updating a few X11 packages from git, I rebooted and everything seemed to work fine. I then shutdown and went over to a buddies, booted up only to see X was locking up my session. I would get a blank screen, and then the system would become unresponsive. I tried re-emerging a few of the applications but the problem still existed.

I instead removed all the keywording for the r500 drivers and the X11 beta applications, and then added back in just the things needed for xorg-x11-7.3. I downgraded everything else, and then my X came back. I then re-added the unmasking and kewording for the r500 drivers, updated everything is now my enviroment comes up. Crazy .. except one small issue. My AIGLX isn't working. 3D seems to work, but I am getting strange errors.

First of glxinfo reports Direct Rendering: Yes. But when I run glxgears, I get an RGB error about double buffering. This seems to prevent any type of compositing manager from running. I tried running Frozen Bubbles, and it works fine. All my 2d acceleration is now working fine, just compositing/3d seems to be borked.

I guess this is the pain fun of working with live git packages
