I believe you can get a expansion serial board for the 5100, but I've
never seem one...

Ok, I'm curious again (and not really that much config clueful)! Given
that the pm attaches to the ibus, and both a 3100 and 5100 have an ibus,
do you make a check for this in ibus.c? I can't see how you'd do this
purely in the config file...
