OpenGL hardware acceleration with FreeBSD 5.3

[Michael Madden]

I have a Matrox G400, and I cannot figure out how to get hardware acceleration
setup for it.  glxinfo still displays "direct rendering: No", and OpenGL
apps like glxgears are slow.  I've made sure I've got the dri and glx modules
loaded, and I've added the DRI section to xorg.conf.

If it helps, here is my xorg.conf file.  Thanks for the help.
