Right.

Well, I'd imagine the main use case for running dpkg-reconfigure in the first
case is 'oh my god, xresprobe got it wrong', in which case you'd want to change
that sort of thing.  But I can see still wanting to probe, and just having the
probe *seed* the default values, so you can change it (but, honestly, it's close
to infallability in Hoary, once I fix a few logic bugs).
