    I haven't done this, but I've seen it done (and it worked). The keyword is
    hotplug (or hotplugd).

    It depends upon whether either device uses the same interface or different
    interfaces, and whether both use dhcp or either uses static IP.

    In my case my wired pc card is eth0, and wireless (older SMC 2632W) uses
    wlan-ng with wlan0 interface. So I could set parameters for each in their
    respective ifcfg files.

    If either your wired or wireless use eth0, there is something in
    /etc/pcmcia that can be used to set different parameters based on MAC
    address (possibly network.opts or wireless.opts).

    It should work without any problem.

    When a PCMCIA card is inserted, the cardmgr should identify the card
    (as expressed by "cardctl ident").
    It then looks in /etc/pcmcia/config for the appropriate driver.
    So there should be no problem at all if things work right,
    as they usually do in my experience.
