Red Hat Linux 7.2 comes with XFree86 4.2.0 and Mesa 3.4.2. The 
Mesa 3.4.2 that is included is the separate Mesa3d project code 
which is patched with the DRI code from XFree86 4.1.0.  The 
reason being for this is that Red Hat Linux supports both XFree86 
4.1.0, and also 3.3.6 X servers and we need to have OpenGL 
support for both servers, using hardware acceleration where 
possible.

The Mesa 3.4.2 which is a native part of XFree86 does not support
software OpenGL with a 3.3.6 X server and hence was unsuitable
for usage in Red Hat Linux 7.x.

Both XFree86 4.1.0 and 4.2.0 come with Mesa 3.4.2.  The one in 
4.2.0 is slightly newer than the one in 4.1.0 I believe - with 
more bugfixes.

Mesa 4.0 was not at a stable enough state for inclusion into 
XFree86 4.2.0, so it will appear instead in some future release 
of XFree86.

Mesa 4.0 now supports OpenGL to 3.3.6 servers I believe also, so 
the hacked mesa would no longer be necessary for 3.3.6 
compatibility.

If time permits, I am considering adding support to my XFree86 
4.2.0 src.rpm for dropping in DRI/Mesa CVS at some point, to 
facilitate easier testing/updating, etc.
