Two things I can think about.

First thing is that you can look at the link lights on the card and try
doing a ping and see which one blinks.

Second, if the machines are the same they should scan the bus in the
same direction and IIRC linux numbers the cards in the order of
detection, especially if they are the same (use the same driver) and
thus it should be consistent with the numbering order of the cards
(they will always get the same number on consecutive boots).
