(I note that I have, in the past, captured crash dumps from head running
on this machine with this configuration.)

OK; I tried this, then booted without attempting to start X in any way.
I then logged in as root and verified that

	sysctl vfs.unmapped_buf_allowed

reported "0".

I then issued "kldload nvidia.ko" (and verified that it was loaded via
kldstat).

I then started xdm, and (as before), got an unclean reboot.  (So: no
difference in behavior as far as I can tell.)

Peace,
david
