Okay, that is different - it leads me to believe that coreboot isn't
turning on your ps2 port.

SeaBIOS does not read keys from the serial port.  If you wish to do
that then add the sgabios optionrom to the flash - see the directions

It's SeaBIOS that implements the numlock led - since SeaBIOS can't
access the ps2 port it wont work.
