indeed, that seems to have been the problem. My startup scripts did set
the correct environment for compiz, but that environment was lost when
I tried to start my session via "/etc/gdm/Xsession default". 

By starting gnome-session directly I get a correctly set up environment.
glxinfo still shows direct rendering to be disabled, but everything
seems to work anyway. I've also tried the matrixview screensaver again
and had no more segfault.
