    When I plug it in and modprobe is triggered to load the driver, a script then
    runs to feed the device appropriate configuration info. Since the driver only
    resets the hardware when it is given the correct configuration, there's no

    Hmm... define "identical". I take a laptop home, use a USB NIC to talk to my
    LAN at home (using NAT) with a 192.168.* address. Then I take it elsewhere and
    use the same model of NIC on the college LAN. All of a sudden, I get myself
    banging on the door complaining about misconfigured NICs :-)

    That sounds a lot like what I've been advocating all along, if that file is
    created/updated by a script when eth0's driver is unloaded, then fed back to
    eth0 on load.

    Yes, that's what we need. A registry, so configuration problems can be
    persistent across boots, and even reinstallations... ;-)
