In this case its already designed, sitting on a combo card with other sections
of the product.  Basically, I get an INTR whenever any of 12 keys is closed
or opened.  I then read 2 bytes from the ISA bus to determine the current state
of all 12 keys.  Comparing this to the previous state I determine which key
changed, then "create" a datum equal to F1 thru F12, as appropriate.  The
puzzle is where to inject this datum into the flow of data going between 
atkbdc/atkbd/kdbio/syscons...

ps.
    I am surprised my mail made it to hackers, I just changed ISPs and reverse
name lookups are still failing, and hub claimed to have rejected the mailing!
