Currently, the order is

keyboard controller
fast a20 port

The second test would hang macbook, so I suggest
fast a20 port
keyboard controller

I don't know if it will break other system. The fast a20 port code is
simple enough, it reads from port 92, modify and write it back, system
that don't support it shouldn't be affected, unless they use port 92
for other purpose.
