That solves that.

The way it works with the new input code is that it modularized the
keyboard/mice from the controller chipsets. This file, q40kbd.c is the
file to sets up the controller chip. For the Q40 we have this as for the
ix86 we have i8042.c. As for the mouse and keyboard driver themselves you
pick PS/2 mouse support and AT keyboard support. These drivers are the
same ones as the ix86 drivers for the mice and keyboard. In theory they
should work on both platforms. Note the check for dev. This field is
filled in when we register the keyboard if it is present.

Yes. Fixed.
