Thanks, I manage to follow linux-pci only very loosely these days...

Unfortunately, this is not correct to do. Many systems report
junk on unused bus number (for example, they decode bus numbers
only partially, so the buses repeat).
In which situation do you need this? Is it on Linux? Only lspci,
or your own code using libpci?
Does `lspci -M' help?
Have a nice fortnight
