if the present the serial ports w/ the same type/sv then it's a major
bug i'd say. as sv supposed to change if the device not software-compatible.
the right way would be to look at the iodc_revision and to not match
the com driver on those values from the K* machines.

you can always disable com in ukc.

can you please show the diffs?
