We allow the request to go through if it matches either a prefetchable or a non-prefetchable part of the bridge. We do not check to make sure it is the right kind of memory because most drivers to not yet properly set RF_PREFETCHABLE (only cardbus seems to do so, and I'm not entirely sure it does it right). RF_PREFETCHABLE was invented for cardbus, so hasn't been properly documented yet. This is still overridable by hw.pci.allow_unsupported_io_ranges, but the need for that is greatly reduced, especially for the nvida driver.
