These numbers are read by the hardware from the on-board EEPROM
and are placed into the InternalConfig register.  The driver
only ever alters bits 20-23 of that register.  I've reviewed the code,
and it looks OK.

Possible the EEPROM is dodgy?  Certainly if you're getting
erratic EEPROM values, the NIC will do strange things.
