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.)
