sorry for beeing an annoying "bastard",
but grep assumes busybox on board
for file in /sys/class/input/input*/device/description;  do
 	if [ ! -f $file ]; then 
		modprobe
	fi
done


but looking around I had a real trouble to find a box beside
my laptop with a PS/2 keyboard attached and it showed the following

 cat /sys/class/input/input*/device/description
 i8042 KBD port

 cat /sys/class/input/input*/device/driver/description 
 AT and PS/2 keyboard driver

as I didn't want to continue my 1 hour search for an eventual PS/2 mouse,
and eventual combinations of the two.
I just applied your patch without the check to the branch timo/panic
