Is it a typo, or...?
According to the documentation the VT82C686 has the following devices on the internal bus: bus 0 dev ? fn 0-6. dev ? being the device of the bridge itself. Re-reading the docs unlike the other the PCI idents aren't fixed so my assumption of dev 0 is actually unsafe. I can't see anything in the doc which guarantees 7 either.
