If you'll be successfull in running NetBSD in simulator your port will run
on hardware with no or just trivial changes.

I'd suggest you take a look and possibly reuse low level stuff
from linux kernel or32 port (linux/arch/or32/kernel/head.S and entry.S, 
can be found in the opencores cvs). This will probably save you a lot 
of time since most of it can be used unchanged (the iTLB and dTLB miss 
handlers, exception handlers...).
