This is about all that can be done, unfortunately. I've never seen
anything useful with regards to this in DMI on the boards I've looked
at, and we would have to rework the board driver -> CPCI hotplug core
interface to pass that information along even if we could get it for
some boards. In general, it is a difficult problem to solve since the
same set of system master and peripheral boards in a different chassis
could very well be at different geographic addresses depending on where
the chassis vendor has placed the system master slot(s).
