    Okay, maybe we're talking at cross purposes here. We do follow the PCI
    core API. We have a __devinit probe and __devexit remove routine, a
    MODULE_DEVICE_TABLE, the kernel generates hotplug events when a device
    is detected or the driver is unloaded, and so on.

    I *assumed* that there was something more that we would need to do in
    order to support real hotplug of actual physical cards, but now that I
    look more closely, it doesn't appear that there is. At least, there's
    nothing in Documentation/pci.txt or LDD3 that indicates to me that we
    ought to be doing more.

    Am I missing something?
