But the driver for those devices have a struct pci_driver object that
they use to register themselves with the PCI subsystem, right? The
MODULE_DEVICE_TABLE uses the id_table structure in the struct pci_driver
object. That's all, it isn't necessarily a hotplug specific thing.
And having that MODULE_DEVICE_TABLE for those drivers will allow the
kernel to load those modules when the bus is scanned for new cards, like
on boot :)
