[kbd] Error on 32-bit system with 64-bit kernel

[Roman Kyrylych]

Hi!

Users who use 32-bit system on 64-bit kernel get this error when
loading a keymap:
sudo /bin/loadkeys -q -u us
KDSKBDIACRUC: Invalid argument

While only very few users use 32-bit system on 64-bit kernel (mostly developers)
it is valid setup and it would be nice to be able to use kbd.
