I'll have to check when it changed, but I can bound it:
2.2.12 is definitely fine,
2.2.16 probably doesn't, and
2.2.17 has the problem.

My goal is to have a single driver that supports both a fixed PCI bus,
hot-swap PCI and CardBus. To support a fixed PCI bus the code scans
existing PCI bus devices when loading.
