   the test development branch is called sommerfeld_i386mp.  the i386 in
   the name is quite significant.  there is no SMP development branch for
   sparc.  all the -current (and probably netbsd-1-6) does is to spin up

well...  that's all it does by default.  but there's this #if 0 in
locore.s you can enable and it will attempt to run the other cpus
and blow up.  it *should* work but i haven't figured out why it blows
up yet (and haven't tried for a long time either, :-( )

   the second cpu.  that's all.  you may want to check the following url to
   compare various ports' status on SMP, etc. :
