So this just looks like a bug in the code - the DT has all the data
needed but the parsing code isn't setting everything up that the rest of
the code needs and/or we should drop one of the ways of configuring
things in the main probe function.  Avoiding having two ways of doing
the same thing in the main probe would definitely be good.
