sounds suspiciously like it may be a switch problem, not a nic problem. When
you force the nic to full duplex, do you have any way of verifying that the
switch port is set for full duplex, e.g. an led or a console for the switch?
You may want to try a different switch port, or better yet switch. Also, you
could try a $15 realtek chipset card(rtk) to futher narrow down if it's the
fxp driver that is at fault. 

I know _my_ fxp cards seem to be fine running on 1.6, but do have a system
that's locking up when amanda runs. I know it's not disk io related, so I
can't say for sure if I don't have the same problem you do. :-|
