There was a defect in the early 3C595 cards (something related to incoming
packet buffer lossage during copyout's). 3COM stated that new versions
of the card with this bug fixed would have a specific bit lit up in
the ROM (or one of the registers?). The vx driver was modified to look
for this bit, and it spits out the warning above if it's not set.
Later, 3COM decided they were not going to fix the defect, so the
bit in question will never be set. Meanwhile, the vx driver has a
workaround for the bug.
That warning message should be removed from the driver probe.
All this was discussed on the mailing lists (probably hackers) back
in 1995 or so (shortly after the 3C595 hit the streets).
