Updated to x.org 7.1 (after a couple days of screwing with getting it 
built) and got it all started up on this i915 machine, and it still has 
the same problem.  If I remove the GLX_RGBA from the attributes passed to 
glXGetConfig, it finds a visual right with no problems.  But adding that 
in causes it to not find any at all.

The code I built is the latest bits from both CVS and GIT.
