xorg cvs server segfaults with indirect rendering

[Roland Scheidegger]

indirect rendering (by disabling dri in xorg.conf) segfaults X here 
sometimes (with a radeon 7200, if it matters). Running glxgears works 
fine, but moving the glxgears window around kills X consistently within 
1-3 seconds. I think this happens since the Mesa 6.3 import (not 
completely sure though).
Here's the excerpt from the xorg log:
    *** If unresolved symbols were reported above, they might not
    *** be the reason for the server aborting.
