I have let the documentation get out of date.  (Sorry.)
The generic kernel is fine:  netbsd-gen.gz

That has not been tested at all, and has only disk boot functions.
I just committed it in hopes that someone might finish it up.
(Actually, the standalone glue has been tested but that's all.)

So for now, you still need the Sun boot program, and some way to 
build kernels with a Sun OMAGIC header format (i.e. cross compile).
