These directives look quite crude.
device-name "ukbd0"; should probably be device-name "ukbd[0-9]+";
Also why kbd0 is taken as new default after ukbd disconnect?
Replacing kbd0 with kbd1 there didn't fix the problem though as I expected.

Following /etc/rc.d/sysconsit looks like in my case "/etc/rc.d/syscons 
setkeyboard /dev/ukbd0" doesn't do anything, since "kbdcontrol -k ${kbd} 
< ${kbddev}" is only called when there is no kbdmux.

Here is another problem:
In the presence of mouse, this command doesn't show ukbd0 attached to 
kbdmux:
# kbdcontrol -i < /dev/ttyv0
kbd1:
     kbdmux0, type:AT 101/102 (2)

Also it looks like the keyboard provided by mouse isn't working. Mouse 
keyboard only has 2 buttons, by default Page-Up and Page-Down and these 
events are never triggered.
Trying to attach it manually, following kbdcontrol(1), I get this error:
# kbdcontrol -a ukbd0 < /dev/kbdmux0
su: /dev/kbdmux0: Device busy

Who is normally supposed to connect ukbd to kbdmux?
