Improved 8042 (AT and PS/2 keyboard controller emulation), no more hacks, split into various devices depending on vendor (generic, AMI, IBM (MCA), Quadtel, Toshiba), and fixed several commands - hopefully fixes all existing AT+ keyboard problems (such as incorrect scan codes on some machine under some circumstances);
