at this point (without trying to activate the device) does ethtool -e still
work? I would assume not.

I looked at your ethregs dump (thank you!!!) and in the EECD register, bit 8 is
not set, indicating the valid bits in the eeprom are not set.
bit 9 is set indicating the hardware tried to read the eeprom.
bit 22 is only valid if bit 8 and 9 is set, but it would indicate which of the
two eeprom banks had a valid signature.

I'm curious if the other bank on the eeprom might still be okay. I'll have to
figure out tomorrow if we can switch to the other bank. I may be able to get
you some internal tools since this is an intel board, I'll have to see what is
available.

BTW this is the first desktop machine I've heard of that reported the problem.
