The diagnostic channel is an interesting idea, but I don't think I want
to build the bitmaps, etc., into the variant hal. The problem of
outputing text on a dot matrix display is generic, not specific to the
board, so should be addressed in a reusable manner.

Ah, I think that is exactly the answer I have been looking for :-)
