--- Comment #6 from Dylan Simon <dylan at dylex.net> ---
It gets farther, and I see acceleration is disabled, but still crashes.  I'm
not sure if this is still related to the driver, though, since, it seems to get
far enough to start drawing windows.  (I should note that once I figured out
that the problem was DRI and installed a new dri2proto, I got everything to
work, so this is a fresh xorg-server built explicitly with --disable-dri2 and
xf86-video-ati built on that with the patch.)
