Alpha has issues with hoses.  That said, this might break some things. :(
If nothing else, it makes it nearly impossible now for people to get the
names of hints to override things like PCI routing via tunables correct.
I would prefer a structured solution that preserved the status quo on
machines w/o multiple domains.  Maybe have the unit number be something
like domain * X + bus number, where X is some arbitrary constant like
100 or 1000 (those are better for human parsing).
