Ahhhh.
Well, I assumed there would be only 1 bridge at all and that resource window would
need to get used for all
devices on cardbus.
So it's actually plain easy to assign resources, even at run-time. I was never able to
see this in action,
because I don't have any PCCards. I won't configure anything at all in that case and
leave it to the cardbus
driver. Anyway, I think it would still be neat to detect the devices (and names) and
put those into detection
area (for e.g. some sort of hotplug-manager).
BTW. why do you need to assign a PCI-bus to the cardbus controller device then? Or is
this needed at all??
