with the patch, committed to -current today, everything will happen 
automatically.

without the patch

# kbdcontrol -a ukbd0 < /dev/kbdmux0 -- add ukbd0 to mux

# kbdcontrol -k /dev/kbdmux0 < /dev/ttyv0 -- switch keyboard to kbdmux/ukbd

# kbdcontrol -a atkbd0 < /dev/ttyv0 -- add atkbd0 to kbdmux

thanks,
