Yes, there is. Device objects without _ADR under the PCI host bridge. Or we can skip the children under every *platform* device created by this by default and mark the ones where we want the children to be enumerated as platform devices too in a special way if needed. I guess we could try that (that was the Rui's original idea IIRC).
