The problem is that when the new-bus code was introduced, the probe order was changed from a bus-by-bus probe (breadth first?) to a depth-first probe. i.e. as soon as another PCI bus is found (e.g. on a bridge chip) it is probed, rather than deferring the probe of the new bus until the probe of the current bus has been completed. I think Doug Rabson had plans to fix the probe order, but it never happened. There is no way to hardwire PCI devices, so you'll probably have to just change which card is referenced in your scripts.
