I'm confused what you mean by this.  Can you please be more specific  
because this can be interpreted different ways.  When I hear "Apple's  
OpenGL", I think OpenGL.framework which has nothing to do with X11.   
The /usr/X11/lib/libGL.dylib that we give you *IS* Mesa GL.  Are you  
haveing problems with that version of Mesa GL that uses Apple-DRI?   
What version of Mesa and what mesa driver are you using that doesn't  
exhibit the problem?

Highly likely.

The fix is to make a Mesa DRI driver for OpenGL.framework and get rid  
of Apple-DRI.  This is on the long list of things to do... =/  If  
you're interested in contributing developer hours to this, I have a  
slew of emails I can forward your way.  Just let me know if you want  
them.

Thanks,
Jeremy
