Usage: kbdinfo [-C DEVICE] getmode [text|graphics]
       kbdinfo [-C DEVICE] gkbmode [raw|xlate|mediumraw|unicode]
       kbdinfo [-C DEVICE] gkbmeta [metabit|escprefix]

If only one argument is given, then just print the current mode to stdout
and exit 0 (unless ioctls returned an error).

If two arguments are given, then print nothing to stdout and exit 0 iff
the current mode matches the mode described by these two arguments.

This interface would be both script-friendly and extensible.
