This is true on at least HP's ia64 & parisc boxes. I believe each PCI controller on these ia64/parisc boxes has its own config space, and can support up to 256 bridged PCI buses, right? Whether or not these PCI controllers share the same IO or MEM space is irrelevant (because it's entirely implementation specific). Ivan.
