I was told that MIPS formally donated the MIPS CO hardware driver
sources to BSD for inclusion in their releases.  However, the
drivers/port never made it into the tree for reasons I've never been
able to figure out.  According to my sources inside mips, they should
have been.

True.  Also, the hardware for it is bog standard hardware: LANCE
ethernet, NCR 53C96, PC Keyboard controller (with different
non-keyboard goo than the PC has), an ISA bus (one slot, and lots of
restritions), and a few other chips that looked familiar.  Even if I
didn't have source to all the drivers, the hardware reference manual
is very complete in its description of non-off the shelf hardware.
