Unfortunately, building DRI2 requires some parts of mesa master
(dri_sarea.h for sure).

If DRI2 was made conditional, then I believe you could do it. I made a
couple changes in both masters on how the generated sources are used
from mesa, but I could easily backport those to the mesa 7.0 branch.

I have patches which kill off symlink-mesa.sh and all the
GL/mesa/Makefile.am's, removing a major source of the breakage, but I
haven't gotten far enough to build GLCore in Mesa. That might be
beyond my current abilities since I'm not familiar enough with the
necessary server interfaces. Unfortunately, you still need the mesa
source at xserver build time to build libglx since it pulls in sources
generated in mesa. Maybe there's a solution to that (libglxapi.so?),
but, again, that would take some more work.
