for the kgbd_machdep.c bits, you should be able to grab the hp300's and
use it unmodified.  For the rest, well, I make sure the "trap 15" handler
is in sync with the hp300's version (in locore.s), and then you have to
add teh serial driver goop (you'll steal this from the sun3 port, for the
most part, probably).

...I haven't done all of the necessary things in trap() yet, for the hp300,
but this ought to at least get you started.
