Thanks to both Polytropon and Arthur for your kind help.

Polytropon's tip to have a look at my kernel config provided the
solution. I had 'device kbdmux' in my KERNCONF _and_ tried to load
kbdmux as a module from loader.conf. This resulted in /dev/kbdmux
malfunctioning, i.e., being absent.

Removing kbdmux from loader.conf allows me to use all keyboards
without further configuration.

Thanks again, cheers,

Punctuation matters:
"Lets eat Grandma." or "Lets eat, Grandma." - Punctuation saves lives.
"A panda eats shoots and leaves." or "A panda eats, shoots, and
leaves." - Punctuation teaches proper biology.

"With sufficient thrust, pigs fly just fine. However, this is not
necessarily a good idea. It is hard to be sure where they are going to
land, and it could be dangerous sitting under them as they fly
overhead." (RFC 1925)
