The ARM11-based cores (architecture v6) have a fairly radically
different MMU and Cache architecture to their predecessors. I have
managed to boot NetBSD on one to the extent that I could get to a shell
prompt, but the code hasn't been in any way optimized to take advantage
of the more efficient architecture and the system hasn't really been
thrashed enough to be sure that it is stable.
