Not all platforms expose the root bridge in PCI configuration space. Intel ia64 platforms do have a materialised root bridge; HP's don't. (I don't know whether Intel ship any PCIe ia64 machines or not). I don't remember details for other platforms, but I think Intel is the odd one out in this regard.
