That's just the xserver DRI2 module, which is optional (pass
--disable-dri2 to xserver ./configure).  The biggest problem is that
the AIGLX DRI loader is now using the DRI interface present in mesa
master.  It should be possible to add a glxdri-7.0.c file to GL/glx
that loads the old-style interface, it's mostly a matter of
resurrecting the old version of GL/glx/glxdri.c and making it compile
conditional on the DRI interface version.

That would be libglapi.so, but yeah, something like that would be needed.
