Things should fail only when two different drivers have requested the same region. NOT when something tells the system that a region _exists_.
The sound driver doesn't fail because two different drivers have requested the same region; it fails because PNP told us a region exists, and the sound region crosses the edge of the PNP region.
Right, and that was a bug.
It *shouldn't* fail. The PnP resource should be inserted _after_ the PCI region has been inserted, and _that_ should fail, since the PnP region is crap and cannot be inserted "half-way".
That means the PNP system driver has to be registered after the PCI driver. We can't guarantee that, especially if the sound driver is a module.
