Glen -- don't worry about it, I've fixed it.
What you do is desolder the old EEPROM (Chipquik to the rescue!), and
set the first six bytes to the MAC address from the barcoded "LNC"
sticker on the bottom of the card. Basically, if the sticker says:
LNC: 1234567890AB
You set bytes 0 through 5 (inclusive) to:
12 34 56 78 90 AB
There isn't a checksum on the MAC address. I guess it just makes sure
the assignee ID ties in with one of Hewlett-Packard's ID codes, and that
the MAC address isn't filled with zeroes or ones...
Still, at least it works now :)
