} I guess I can probably remove those changes.  So we'll have to rely on 

     Although, you can't test them, possibly keep them.  We do want to
support hotswap PCI at some point.  Also, dyoung@ is in the process of
merging cardbus into PCI.  I don't know if your changes would cause
mod_verbose to be autoloaded for cardbus, which uses PCIVERBOSE, but
cardbus insertion should be handled at some point.  And, of course,
there is PCIe and expresscard on the horizon.  expresscard is basically
hotswap PCIe along with USB (i.e.  an expresscard slot brings out
signals for both and the card determines which one it is going to
use).

} The only thing I find that uses libpci is /usr/sbin/pcictl and that 
} seems to be working fine.

     What about X?  What does it use for scanning the PCI bus?
