Btw, even without actual physically plugging in the device, at least the 
really early KVM boxes used to basically just _physically_ switch between 
keyboard ports, and so using such a KVM switch is essentially also going 
to plug it in after boot time.

Some slightly more fancier KVM devices (probably most of them by now - if 
you want auto-switching etc) have real electronics and actually emulate a 
keyboard, needed for computers that require a keyboard to even boot up 
("Keyboard not detected. Press F1 to continue").

But the hard-switching ones were at least at some point way more reliable: 
the "smart" ones would have trouble with any "fancy" features like 
scroll-wheels etc. Probably not an issue any more.

Of course, these days few people use PS/2 keyboards any more, but it would 
still be a shame to break a perfectly reasonable setup.
