In that case, these are the outputs I get (still with stock 2.4.5
driver):

 The EEPROM checksum is correct.
Intel EtherExpress Pro 10/100 EEPROM contents:
  Station address 00:90:27:94:21:CA.
  Board assembly 721383-006, Physical connectors present: RJ45
  Primary interface chip i82555 PHY #1.
   Sleep mode is enabled.  This is not recommended.
   Under high load the card may not respond to
    PCI requests, and thus cause a master abort.

 MII PHY #1 transceiver registers:

  0000 0000 0b20 0000 0000 0000 0000 0000.
  Baseline value of MII status register is 782d.

at this point it seems to hang, I can Ctrl-C the process and it dies,
otherwise it just sort of sits there doing nothing for about 2-3 minutes
and eventually exits having outputted no more information.

Doing that produces this:

-(root@tenshu)-(/opt/home/cmsj/tmp)- ./eepro100-diag -ee -G 0 -w -f

Would write 40a0 to the chip configuration word 10.

so it looks like the config isn't actually written to the card.
