The agp issue aside, I was able to track down where the crash
occurs (without the agp, of course): X crashes the machine
during init (xf86MapVidMem) in the call to i386_set_mttr from
NetBSDsetWC() in hw/xfree86/os-support/bsd/i386_video.c.

As far as I can see, this has nothing to do even with what
driver I'm using (I'm currently trying to use vesa).


About the agp issue: I looked at intel docs for the chip that
is in T61p, and the current NetBSD agp drivers most certainly
won't support it, because the chip is not a Host-AGP bridge,
but a Host-PCI-E bride. For example, it does not have the
AGP_APBASE register -- in other words, it does not have the
apreture system.
