i would double-check the no name brand thing on the cards. look for
the actual chipset instead of the manufacturer. might help identify
the card physically. but i agree with pete, dmesg's help ;)

that being said, i once had a very odd issue with dc(4). i had ONE
physical DEC card in a random x86 box, but the system swore up and down
that it had two. i never figured it out - though, that was a few years
ago now, so who knows....
