Understandable, considering PS/2 is not technically hot-swappable...Be careful
doing that, cause I've seen machines stop responding to PS/2 input after a
"bad" swap...I don't know if the on-board keyboard controller gets fried or
what, but swapping PS/2 peripherals is just something I don't do any more.

As far as why FreeBSD doesn't recognize PS/2 hardware after it's hot-plugged,
I can't help you there. You might consider looking at the flags for the
drivers that work with the keyboard.
