At this stage I'm not doing anything with the interfaces beyond trying
plug in a cable and configure an IP with ifconfig.  A few more details
that might be worth mentioning:

* The system does have the built-in Integrated Management Module (IMM)
that has its own dedicated Ethernet port.  I've done nothing with it.
* If you do happen to plug a cable into this management NIC, within a
few seconds the box does a reboot (!)


I'll test the patch within a couple days.  Thanks!
