kbd            - 8042 (yeah THAT one - is it ENDIAN clean?)

Everything it uses is 1 byte, so there shouldn't be any endian issues
at all.  OB-)

   I'm certain there are drivers for the wd37c65 and the mc68230
   somewhere, but no one seems to identify their hardware in the
   source!

The wd37c65 is one of the standard chips used for PC floppy drives.
You should be able to make the i386 `fd.c' work in your port.

I don't know about the mc68230.  (Is it really used for both clock and
parallel?!)
