I'm experiencing the same problems on a thinkpad with an Intel Mobile GM965/GL960.
I noticed two things:
1) GL-applications seem to work better (less flickering, less textures missing) when compiz is turned off (tested with glxgears and google earth)
2) There is no hardware acceleration available which explains the low framerates (do a 'glxinfo | grep direct' to check on your machine)
jan@jan-x61:~$ glxinfo | grep direct
direct rendering: No (LIBGL_ALWAYS_INDIRECT set)
