OK. 5% of the work is done. Good luck writing the SMT code. If you have
somthing working I will be glad to test it on my NPI DAS card. 

BTW: How much throughput do you get from that NPI card and what SPARC
does it live in? I got only 2.7MB/s when I did a quick test and the CPU
(SS5, 110MHz, Solaris 2.6) usage was 100%. It seams that this card is
quite suboptimal designed. (Compared to a DEC DEF[TEP]A) 

The point with NetBSD SMP on SPARCs seams to be mostly a lack of
developers with time to do it. The NetBSD developers do everything
as machine independent as possible, most prerequirements are solved 
in a machine independent fashion. (AFAIK) So most of the SMP stuff 
is in place. The upcoming 1.6 release will have SMP for VAX and Alpha.
