First of all I admit that I haven't been following closely, so I maybe way

Anyway, the old ISAPnP used, AFAIR, struct pci_bus for the card and struct
pci_device for the devices. So what's wrong with using the basically the
same abstraction with the driver model, which has buses and devices as
well. That means each device can have its own driver, and I suppose that
should be good enough (as opposed to only one driver per card).

But probably I'm missing something?
