The machine is directly connected to our lightly loaded 100mbps backbone. I can't imagine that all these timeouts are caused by collisions; remember that collisions are a normal occurrence on an Ethernet unless you are dealing with a full-duplex link. For a transmit timeout to be caused by collisions, 16 collisions and retrys have to occur. Keep in mind that every single transmit times out with kernel 2.0.30; but things work fine with 2.0.29. Whatever the problem is, it's not entirely hardware related.
