Quick update --

  * I've managed to get AIGLX working on my r300. I'll talk with pkgsrc
    folks on how to upgrade our MesaLib package to support DRI.

  * Had to modify Xorg to link against libpthread to make AIGLX happy.

  * After fixing up agp_via in the kernel (and enabling AGP support in the
    Xorg radeon driver), performance has doubled according to glxgears:

 	10501 frames in 5.0 seconds = 2100.059 FPS

  * That score, by the way, was captured while running GNOME 2.16, AIGLX,
    and compiz + gtk-window-decorator, with all of the fancy wobbly /
    expose / fade / etcrap plugins active.
