As I wrote before, when the console device, sc or vt, is present, the
keyboard is exclusively used by the console driver.  You can remove or
disable the console driver to prevent this.

Or pull out the video card.  When a video card is not present, the
console driver won't be installed.

    kbdcontrol _whatever_ < /dev/kbd0
