I'm not sure you will be able to run netbsd without a fpu. I think a
kernel with NS381 defined will just halt at some point because there is
no way to determine the presence of a fpu at runtime. At the moment the
kernel will try to save the fpu state, the cpu will halt. You might be
saved due to the lazy fpu state save... If you need a fpu I probably
have a B0 stepping somewhere. It has the divide bug, but at least it
will enable you to start.
