Thanks to you're reminding me of Stefan Reinauer's PDF I might be able
to take a stab at it. The key sentence from the "pci" section is: "The
first occurrence of the pci keyword tells LinuxBIOS where the bridge
devices start, [and this is the key part] relative to the PCI
configuration space used by the bridge." So, in my case the ht1100
starts at DID 1 (let's call that bridge DID or DIDb) and devices are
enumerated as DIDb + 0, DIDb + 1 and so on. If I look at it that way I
can deduce when 0 is needed. Does that seem correct?

I did post the Phoenix BIOS since I'm currently unable to boot using
LinuxBIOS.
