Sorry, I was rather unclear there.  The HIL driver has its own built-in
keymaps.  What I'm seeing (for example, when I press the `g' key):


or sometimes


or some other permutation.  I would prefer to not worry about this for
the moment; there's lots of other things to tidy up and it'll probably
sort itself out once something else is done properly.

I've now committed most of my changes.  I'm _not_ committing this one
as it'll definitely screw up every other type of machine:

(please excuse the copy & paste)

If you have a 715/33, you may wish to apply the patch and watch in
amazement as your keyboard produces characters.  Hopefully we'll thrash
out how to get it working properly soon.
