I see the right way to do this is to make the default behaviour the 
'guaranteed no break boards' behaviour. That means default value is to 
scan all busses. For those who need/want it set lower, they can know 
where the config option is.

But we sure oculd use an addiiton to the wiki that explains stuff like this.

make sense?
