Probably just a bug.  A quick scan of $bus in the configurations shows
that we've only ever used it in cases where it was the complete string
(ie "$bus") and even then, only used to populate numeric interfaces with
the bus number to be used programmatically by downstream sensors.

Some of the intent was to largely remove the bus number from the device
naming convention, as outside the system the bus topology is largely
irrelevant.  With that said, I could see how that might be desired for
some setups.

James is out the next few days, so his answer might differ from mine
when he gets back, but I don't think we knew about this issue previously.
