Thanks, I've merged the first batch of changes, I'm going through the 
rest of the patch now.  Once I get that committed, are you planning to 
merge Xgl to head?

On a related note, I saw this commit:

http://webcvs.freedesktop.org/xorg/xserver/xorg/GL/mesa/X/xf86glx.c?r1=1.5.8.5&r2=1.5.8.6

and I don't understand why you need the GlxFlushContextCache() calls. 
In the loseCurrent case, StopUsingContext(prevglxc) is called later in 
DoMakeCurrent which clear the context cache.  In the destroy context 
case, ctx->destroy() is only called from __glXFreeContext() (except for 
DoCreateContext) where the context cache is also cleared.

cheers,
