As I understand it the PKGBUILD will also have to be altered.  The
driver will be built by default but not installed to
"/usr/lib/xorg/modules/dri/" as mentioned by Stafano.  The purpose of
having both drivers built is so that one could experiment with the
gallium driver with export LIBGL_DRIVERS_PATH = ... before executing
particular opengl programs without switching outright.

I've been doing this for a couple weeks now with the git version of
just the r300g driver running with Arch's packaged mesa 7.8 and have
found that it has fixed all the bugs I was having in Neverwinter
Nights and eduke32 with no new problems besides the occasional
stuttering when fps drops too low.  I would vote for making it the
default in Arch with mesa 7.9.
