    $(':checkbox').bind('click', function(){
        if($(':checkbox:checked').length >= 5) {
            $(':checkbox').not(':checked').prop('disabled', true);
        } else {
            $(':checkbox').not(':checked').prop('disabled', false);
        }
    });
    

    Note that prop is jQuery 1.6 exclusive. In case of jQuery < 1.6 use attr.
