Host bridges and other PCI stuff can be probed even in early system
initialization, Phillip Rumpf wrote some code to do that. But for the
SuperIO stuff, which is often(always?) not done in PCI hardware, you
don't have a descent way of probing. This could be handled by variable
areas in the bios image like the ESCD stuff. Is this what is done via
the LinuxBIOS table?

Exactly. Hide the specific stuff early and handle pci initialization in
a more generic per device way.
