I wanted to use the keymap file /usr/share/keymaps/i386/qwerty/cz.map.gz,
but I have found this to be qwertz so I think it should be placed in
/usr/share/keymaps/i386/qwertz/ (or, much better, converted to qwerty -
I don't understand the masochists who use us-qwerty and cz-qwertz together :-)

Gentoo notes:
We copy the qwerty/cz.map to qwertz/cz.map and then apply this patch ...
that way we end up with both a qwerty and qwertz version of the cz.map
