I have two different linux boxes and a number of 3c905C Tornado's - a few
are made in ireland but most come from singapore and has a different chip on
it. I mention this because only the ones that says made in ireland works
100%. I've switched pci slots, cables and switches/hunbs around endlessly,
and here's what I've come up with: (they are now both connected from the
same machine and to the same switch, a 3com 'OfficeConnect - dual speed
switch').

One thing I've noticed is that the autonegotiated capability is 0140 on the
'bad' NICs and 01e0 on the 'good' NICs and negotiation both says completed
and not completed with the 'bad' NICs.
ping flooding through the bad NICs results in a lot of RX errors and RX
frame errors (~5 %), but I've seen 10%+ when the box was doing something
useful instead of just the pings.
