Acckkkk!!
Well, at least you asked instead of reporting a bug later.

The driver is working correctly.
All of your connections *should* be half duplex.
Forcing full duplex will cause massive performance and correctness problems.

'Ping' will work, and everything else will be horribly slow and unreliable.
Some types of network cards will freeze for a seconds at a time when
presented with out-of-window collisions.

On an unrelated topic, I'm working today on updating the "kern-2.3" drivers
to work with the recent development kernels.
