In absolute pointing mode the keyboard is virtually unusable since
the keys are too tiny (just 8x6). There are other issues too: for
example putting the keys on top doesn't make sense on touchscreens
and there is a lot of empty space in between keys that serves no
real purpose.
Until these issues can be addressed properly simply force 3x3 mode
when in the keyboard.
