Code Example

add_filter('media_upload_tabs','wpse13567_media_upload_tabs', 99);
function wpse13567_media_upload_tabs( $tabs ) {
    if ( wpse13567_post_has_attachments() ) {
        unset( $tabs['type'] );
    }
    unset( $tabs['type_url'] );
    unset( $tabs['library'] );
    return $tabs;
}
add_filter( 'media_upload_default_tab', 'wpse13567_media_upload_default_tab' );
function wpse13567_media_upload_default_tab( $tab ){
    if ( wpse13567_post_has_attachments() ) {
        return 'gallery';
    }
    return $tab;
}
function wpse13567_post_has_attachments(){
    static $post_has_attachments = null;
    if ( null === $post_has_attachments && $post_id = (isset($_REQUEST['post_id']) ? $_REQUEST['post_id'] : false) ) {
        $post_has_attachments = count(get_posts("post_type=attachment&post_parent={$post_id}"))>0;
    }
    return $post_has_attachments;
}

add_filter('media_upload_tabs','wpse13567_media_upload_tabs', 99);

function wpse13567_media_upload_tabs( $tabs ) {

if ( wpse13567_post_has_attachments() ) {

unset( $tabs['type'] );

}

unset( $tabs['type_url'] );

unset( $tabs['library'] );

return $tabs;

}

add_filter( 'media_upload_default_tab', 'wpse13567_media_upload_default_tab' );

function wpse13567_media_upload_default_tab( $tab ){

if ( wpse13567_post_has_attachments() ) {

return 'gallery';

}

return $tab;

}

function wpse13567_post_has_attachments(){

static $post_has_attachments = null;

if ( null === $post_has_attachments && $post_id = (isset($_REQUEST['post_id']) ? $_REQUEST['post_id'] : false) ) {

$post_has_attachments = count(get_posts("post_type=attachment&post_parent={$post_id}"))>0;

}

return $post_has_attachments;

}

Code checked, works great.
