I have had a hard time getting any further information about this problem, and can not say precisely which component is causing the crash. On a Powerbook3,2 with a Rage Mobility M3 AGP2x, I experience a crash every time I start an OpenGL application (after the first frame is drawn). The problem seems to persist regardless of whether or not direct rendering is enabled. I am not using XOrg CVS, but am using XOrg 6.8.0.
Possible duplicate of bug #1513.
Does the system actually crash, or does the OpenGL app and X hang? Do you have another box that you can ssh into the Powerbook? If so, then this is a dup of #1513. The other thing you can try is to open two xterms. In one do "sleep 60 ; killall glxgears" and in the other do "glxgears". Wait a minute (literally). If glxgears is killed, then you have a dup of #1513. This is fixed in Mesa CVS and will be in X.org 6.8.2.
After reviewing the discussion in the Gentoo forums associated with bug #1513, this bug is almost surely a duplicate. *** This bug has been marked as a duplicate of 1513 ***
