    Just FYI for those following this thread; testing the server and 3D
    drivers really isn't too much trouble these days, you can even install
    everything into a separate path (I usually choose /opt-gfx-test); you
    just need to build libdrm, mesa, xserver and your video driver (along
    with an input driver or tw) in that order. Then just startx
    -- /opt/gfx-test/bin/Xorg and put something reasonable in .xinitrc.
