Geert, Thomas, Shao,

Results of add the printf:
eepro100 - mdio_register: 0xffff

Results of 'lspci -vn -s 02:07':
02:07.0 0200: 8086:1209 (rev 10)
    Flags: bus master, medium devsel, latency 32, IRQ 16

I'm not seeing a 'subsystem' entry for that command. Here are the results of
'lspci -vn' for completeness:
