This says that this interface is recognised, and has sent 12 packets,
and received 11. This is promising...

I presume, you pinged this from the Mac?

Could you type /sbin/arp -a to see if the MAC address on the Mac is in
there?

This means that networking has come up correctly, so the most likely
suspects now are the cable, or one of the cards working at 10Mb and the
other at 100Mb. I don't have experience debugging that.

Does anyone on the list know if it's possible for windows drivers to
notice a patch cable instead of a crossover, and transmit accordingly?

No problem. I'm impressed with you typing that stuff out...
