If you see a device at, say, 0x31 and 0x51 which both seem to be eeproms, then they are most likely the same device responding to either address. Don't count on most eeproms to show up twice like this, though. It is possible to have devices in the 0x30-0x3f and 0x50-0x5f be independant, unqiue devices. It appears to be rare (at least on motherboards). I hope this helps.
