/*
 * NOTE: The AT/MF keyboards can generate (via the 8042) two (MF: three)
 *       sets of scancodes. Set3 can only be generated by a MF keyboard.
 *       Set2 sends a makecode for keypress, and the same code prefixed by a
 *       F0 for keyrelease. This is a little bit ugly to handle. Thus we use
 *       here for X386 the PC/XT compatible Set1. This set uses 8bit scancodes.
 *       Bit 7 ist set if the key is released. The code E0 switches to a
 *       different meaning to add the new MF cursorkeys, while not breaking old
 *       applications. E1 is another special prefix. Since I assume that there
 *       will be further versions of PC/XT scancode compatible keyboards, we
 *       may be in trouble one day.
 *
 * IDEA: 1) Use Set2 on AT84 keyboards and translate it to MF Set3.
 *       2) Use the keyboards native set and translate it to common keysyms.
