One other alternative would be to introduce a braille driver parameter
to enable compatibility to other display types in the Baum driver, and set it
to off by default.  This way, a user that is using the compatibility modes
of a Vario could enable this easily in his/her config file,
and the other users would be protected from false-positives by default.

Yes, after I sent the mail I remembered that I was once using
a Vario 80 which also had the compatibility modes.
