The 3c509 driver is still a bit flaky, I'm sorry to report.
I was setting up a router a while ago where I wanted to
install a total of 5 3c509 cards.  This was an older 486/66
with all ISA slots and a SCSI card, and no serial, parallel
or rodent port cards in it.  I was able to get the ep driver to
recognize all 5 cards, but no matter how I switched the interrupts
and ports around with the 3c5x9cfg program, I could never
get more than 4 cards to actually send and receive packets on
the Ethernet.  (and yes I had all other nic drivers disabled)
I've also had weird problems with 3c579 cards in EISA boxes
which use the same driver.
