Hmm makes sense why NetBSD wouldn't use FreeBSD's kernel code.  Alright then.  Thank's for the information Eduardo.

There's really no point in looking at the FreeBSD code.  FreeBSD has a completely
different design for the low level kernel code.  As far as what's needed to 
do the SMP stuff for NetBSD, that's pretty well known.  I just never had a SMP
machine to play with.  And now I doubt I have the time.  I haven't even gotten
around to working on the UIIIi machine in my office.
