Update a thematic child-theme for wordpress 3.0 menu

The new menu system in wordpress, while not perfect (yet), is a huge step in the right direction. I have had to update many old themes to support this feature, and as most of my theming is down with thematic, I finally got a standard block of code together to add to a functions.php file of a child theme to add theme support for menus and add them to the theme. Here is the code, all you do is add it to your functions file and then you can manage menus thorugh the new menu page in your pw dashboard! Enjoy!
[cc lang=”php”]
//// Add support for new menu in WP3
// declare that our theme supports wp_nav_menu()
add_theme_support( ‘menus’ );

// Register the a new menu for the theme called “Primary Menu”
function register_primary_menu() {
register_nav_menu( ‘primary-menu’, __( ‘Primary Menu’ ) );
}
add_action( ‘init’, ‘register_primary_menu’ );

// Remove the standard Thematic menu
function remove_menu() {
remove_action(‘thematic_header’,’thematic_access’,9);
}
add_action(‘init’, ‘remove_menu’);

// Create the new wp_nav_menu called “Primary Menu” in theme
function new_access() { ?>
