Yepp, you are right, identyfing a ps/2 device is sending the device
some strange ps/2 request combination (like set sample rate 02, set
sample rate 01, set sample rate 00, get resolution) and look how the
ps/2 device reacts. In FreeBSDs ps/2 implementation you can't do this
From user space. (You could if you do same really bad hack, like
direct i/o and /dev/kmem stuff, but that does not count ;))
