There are two chips on the motherboard (visual inspection :-) both say 920.
Now I don't know whether a 3c982 card actually would also have two chips
on it.

I have compared the 3com driver (version 1.0.0i) with the 3c59x driver
a while back (http://www.sfu.ca/acs/cluster/nic-test.html) with the
2.2.16 kernel. At that time the 90x driver was so much worse (particularly
with upd) than the 3c59x driver (besides not supporting channel bonding)
that I never used it again. Your note indicates that this is probably
still correct.
