Afaik the SuperIO chip used in the Cobalt implements those registers but
due to missing external circuitry touching some of these registers is
dangerous.  Afaic that is the case for the PS/2 keyboard/mouse controller
ports.  So those should be marked as reserved.  The remaining registers
are implemented just not terribly useful, so I think what he have is
probably right as it is.
