A comment on the kbd interface:  in addition to the keycode
member, we should also have a scancode member.  Some applications
want to see the kbd in scan code mode, others want to see the
keystroke.  There should also be a way to put the RTEMS
kbd driver to and from scancode/ascii mode, also.

With PC keyboards, some applications need to know whether
the keypad arrow key or just the arrow key was pressed.  The
scan codes are the same, just a different prefix byte from the 
kbd controller.  So there should be a bit set for that too; I guess
that can go into the modifiers member.

Greg
