OK, that clears the sleep mode bit, which causes PCI protocol errors.
You must cold power cycle the machine for this to take effect.  (There
is no way for the driver to clear the bit during operation, or the
EEPROM-setting step wouldn't be needed.)

The Sleep Mode bit was definitely one problem
If cold booting didn't solve the other problems, blame the last person to
modify the driver...
