I doubt if the MTRR setting is responsible for the server crashing,
but you can always build a kernel without options "MTRR" to be sure.

The next thing that's supposed to happen, is that the driver completes
softbooting the card, so it looks like that's where the bug is in the
driver. One idea -- you might try invoking the "r128" driver directly,
rather than letting the "ati" driver do it. See
"/usr/X11R6/lib/X11/doc/README.r128".
