It's probably easiest to pretend your HW has PCI, yes.
Alex is suggesting that it would be easier to pretend you have
one of the existing PCI host controllers as well. I don't know
if that's true or not; e.g. pc_piix.c seems to have lots of
pc-specific stuff inside.
But it probably doesn't take more than 100 lines of code to give
guest access to the pci config and i/o space. It's likely to be
comparable in size to any other private bus that you'd invent.
