I'm confused, too ;-) The "fpu0 at mainbus?" line comes from the 
SMALLRAM template, that comes with the sources and which is optimized 
for a 68030 machine acting as PPP-gateway. You should see it further 
down in your config file, not in the "CPU support" part at the 
beginning. Maybe this option doesn't even exist any longer, since all 
this is from the NetBSD 3 sources.
