We had a lot of problem with scancodes and superHermes. We decided to
cope with only one type of scancode (there are three mainly different
schemes)
I guess it is that the hard coded keyboard routines in Peter's logic
chips does not cover some scancodes CueCat are using.
It will be Q40 and not Linux (or SMSQ) I think.
