I've investigated this deeper, and apparently it shouldn't be a problem.
Mesa takes care of the driver capabilities for the GLX visuals and 
and you have an intersection of what the server advertises and what you can
actually have.

The only constraint in the spec seems to be that there must be a GLX 
fbconfig supporting
RGBA and some other constraints.
