Nasty 0xe0 logic is gone.  We map through QKeyCode now, giving us a
nice, readable mapping table.

Quick smoke test in OpenFirmware looks ok.  Careful check from arch
maintainers would be very nice, especially on the capslock and numlock
logic.  I'm not fully sure whenever I got it translated correctly and
also what it is supposed to do in the first place ...
