The '040 definitely has its MMU off.  However, I'm unsure whether
the initial '030 (pre-accelerator swithch) has its MMU off.  Well, actually, 
I'm not too sure  -- before I asked a question to newsgroup whether logical 
address 0 was equal to physical address 0 when netbsd hit the start symbol.
And the general consensus was no, that was not true -> ergo, my belief that
MMU in the '030 must be off.
