I don't think the EEPROM is the problem.

Hmmm, these are not likely correct.

That's definitely bogus.  The chip doesn't exist in I/O space.
Run pci-config, or something similar, to see if the chip is in ACPI power
down mode.  But this isn't likely -- some program would have to put the chip
to sleep.

This is just the result of the 21143 chip not existing in I/O space.
