This is a system-specific thing. As noted previously clearing flag 0x1 on
atkbd0 can help this, but it doesn't always work on all motherboards.  To
do this, edit /boot/device.hints and make sure there is no
"hint.atkbd.0.flags" line. Reboot to have the change take effect.

_Technically_, ps/2 is not hotplug -- you risk severe electrical damage to
the system by hotplugging ps/2 keyboards and mice.  If you do this
frequently you may consider investing in a KVM.
