No, I didn't understand it this way. It's fine then

Yes. I'm not sure you need a new /dev/pci. /dev/pci* can already handle
requests for all PCI busses as the PCI bus number is passed in the
ioctl command (your way of retrieving the softc to use the correct
pci_chipset_tag_t is better, BTW). I think all you need is a way to do a
PCI_IOC_BUSINFO for an arbitrary bus number and not the one designed by
the device's minor number. A new ioctl would fix this.
