possibly the later :)

well, it may or may not work, depending on whether you want or don't
want to use both keyboards at the same time

well, you should be using keyboard name (not keyboard device node
name) in attach/detach, i.e. something like

% kbdcontrol -A ukbd0 < /dev/ttyv0

to detach ukbd0 from kbdmux. as you have realized, you can not do
anything to a keyboard if kbdmux has control over it. so, you need to
detach keyboard first. because kbdmux is essentially "master" keyboard
if you set keyboard map on kbdmux, it will set the same keyboard map
on all the "slave" keyboards. you might want to try

- detach keyboard from kbdmux

- set map on detached keyboard

- reattach keyboard to kbdmux

kbdmux does not set map on KBADDKBD ioctl(), so, in theory, it *might*
work. also, please keep in mind that kbdmux will always set "slave"
keyboard into K_RAW mode.
