As I can't remeber if Xgl/3D is the one that requires open drivers.
But the answer is that as far as I know only the binary NVIDIA drivers
provide 3d accelerated xinerama support. That is probably your problem
if you don't that NVIDIA hardware, and drivers. The problem if you
want to know is that xinerama works by rendering the entire display on
every screen and then only showing the proper part on the proper
screen.
