Doesn't it have enough information at the time the PCI space is mapped into user space to know what that PCI space corresponds to, and/or to know that if an area of PCI space has been mapped into user space (and not subsequently unmapped) that it shouldn't be given to a newly inserted device? Also, I think that unmapped PCI ROMs are only mapped in (to PCI and user space) by XFree86 long enough to read their contents, but I'd need to double check that. I'm sure I'm missing something. I'm just trying to figure out what it is.
