Okay, now I'm totally confused...

As I said, the IDPROM seems to be set correctly to a valid mac id, hostid,
and checksum. On a whim, I did an 'arp -a', though, and discovered that the
ethernet device seems to believe that its mac id is all zeroes.

I can understand the zeroes if the battery were dead, but why am I seeing a
valid value in the IDPROM and banner?
