Uhm... Stranger and stranger...
What are the two cards? What Kernel you running? Post the contents of /proc/pci , /proc/interrupts & /proc/ioports maybe it'll give someone a hint. The other thing you might want to try doing is reading up on the code for you NIC and seeing how to force full-duplex, the driver may just default to half-duplex if more than 1 card is present for some strange reason (maybe just to confuse people!! )
cheers
