I understand. However, I've tried three different (identical chipset) cards.

It is completely symmetric:
A->B ==> A.TX++, B.RX++
B->A ==> B.TX++, A.RX++

For the question of cabling, I've tried connecting two machines with a
crossover cable (using two distinct cables). I've tried connecting the
machine with the MPX cards to a 3com 10/100 switch and accessing it from
other hosts on that switch (again, using two distinct cables).
BTW, the error I mentioned in my last post came back up. It's:
eth0: Oversized Ethernet frame, status 2900a50d!
eth0: Oversized Ethernet frame, status fb9fcca8!
