Only in that each turns on PCI debugging code.  The difference is that
with what I sketched, the debugging code it turns on is code you add,
whereas the debugging code pci_conf_debug turns on is code that's
already there (though code you add can of course be controlled by
anything you want, including pci_conf_debug if you choose).
