I have a device that changes this value (a GatorBox), and I believe
under some versions of Ultrix, they reprogrammed the ethernet
address as well (if I remember correctly, it was in conjunction
with something to do with DECnet).  So although an address is
stamped on the card, the system reports a different one.  (Don't
know why this is done, and it seems to make little sense as it
could cause a conflict?)
