You mean you add devices through sysfs? That's another approach I was 
thinking I'd follow, except it still doesn't solve my problem... meaning 
I have no reliable way of telling the numbers assigned to the busses added.

*COUGH...COUGH* Oh, that was on purpose... *COUGH...COUGH* so to see 
whether anyone was paying attention. Good catch! :-)
