Add new 'setkeyboard' method to the /etc/rc.d/syscons. It accepts the

keyboard device name (i.e. /dev/kbd0). This method will do nothing is
kbdmux(4) is the current active keyboard, otherwise it will switch
active keyboard as requested.

Modify ukbd(4) entries in the /etc/devd.conf to use /etc/rc.d/syscons
and new 'setkeyboard' method.
