You only need to create this script if you don't have a default 101 keys US keyboard layout. Create a new file /etc/init.d/loadkeys containing the following:
#!/bin/sh
# Begin /etc/init.d/loadkeys
source /etc/init.d/functions
echo -n "Loading keymap..."
/usr/bin/loadkeys /usr/share/keymaps/<arch>/<layout>/<keymap> >/dev/null
evaluate_retval
# End /etc/init.d/loadkeys
Replace <arch>, <layout> and <keymap> with the proper directories and filenames to match your system and language.
