The "implementation" in the drivers is "correct" and is required to 
advertise 1.3.  The real problem is that GLX support isn't there. 
There's no support in glXChooseVisual or glXGetConfig (and in any of the 
supporting infrastructure) for the multisample enums.  There's a couple 
other problems.

In any case, I'm working on fixing the GLX support.
