Humm, I've never seen this myself. Please describe a situation I can try
and duplicate were an interface that does not have IP bound to it would

This _does not_ work. I have tried this with both switches and hubs from
3COM, Cisco, D-Link & Netgear. Cutting the TX lines means you can not
initial the port to establish link. No link means you will not see
