So make sure that you build a mipsel image.  This can just be part of
our standard kernel config, actually.

yamon is MIPS' boot load/prom monitor that MIPS sublicenses to other
companies.

It looks like these have their own boot monitor, and without detailed
technical specs I can't tell which port would be the best baseline. 
evbmips isn't a bad first choice, I think.   You could probably also
look at algor.

Unfortunately, evbmips (and Alchemy in particular) is really the only
NetBSD port I have experience with, and I'm still pretty new to NetBSD
itself.
