It would be good to know.

But not on the same port. I've seen hardware combinaisons that would'nt
renegotiate the same thing accross reboot. One time it works, another it

No, as the link behavior isn't symetric in this case.
things will be worse on the local subnet if the remote machine is
full-duplex. However if it's half-duplex you'll see almost no
collisions on your link.
What driver do you use ?
Does netstat -i show errors on the interface ?
