I'm not sure what ge.conf is. All I know is that the driver can be
set to various forced speeds via the ethtool tool, the config file
thing depends on whatever software package you have I don't know
about.

Yes, that's normal. Some hubs/switches won't properly work with
autoneg, so the kernel has to try forced speeds. The proper way
to turn that off is to shut down the interface using ifconfig
(or /etc/init.d/network).

I know there are some laptop specific tools that monitor the link
and do the shutdown of the interface when there is no link but I
don't have any precise pointer at hand.

Ben.
