Grant has a specific built-in NIC with an unusual transceiver reset
timing requirement that cannot be specified with the media table.
His problem is not a general one, and it's certainly related to your
problem.

Use a different driver version.

That driver is based on mine (despite removing the copyright information
from the output and binary), but it's derivative code.  I can't help you
with the specific problem, but can confirm that it is broken...

Hmmm, no media information.  I don't know if the output has been
removed, or if this version isn't reading the EEPROM correctly.

This is better.
