It'd have a hack value to design and implement "portable ROM monitor"
:-) to provide a handy set of ROM subcalls and sexy interface helpful
for development cycles.  It's a fun to have glueless interface with
NetBSD libsa.  Building useful ROM monitor is a real burden to bring
new hardware into market promptly.  Larger computer companys have
inhouse design and software assets reusable to new hardware design.
It's sort-a muscle to win in the fast paced buttle field.  It's even
possible to make money to implement and sell portable ROM monitor if
it's handsomely realized.
