The keymapping on my Japanese keyboard changes quite a bit when it's
set up to use set 3, instead of the default set 2.  I've temporarily
switched back to using set 2, until I've got time to set it up
properly, but the language keys don't function in set 2, (they
generate the same scancode as the space bar).

Let me know if I can provide any extra info from this keyboard - it's
an IBM 5576 Keyboard-2, part number 94X1110.
