Currently, there isn't a version of NetBSD that runs MMUless. Running
without an MMU would require some pretty extensive changes (like
ripping out the UBC system, replacing fork()+exec() with spawn(),
eliminating use of mmap, etc.)

We (Wasabi) have thought about doing it a couple of times because
sometimes embedded customers come to us wanting MMUless CPUs to run,
but it would be a *lot* of work.
