If anyone is running the bleeding edge nighties of WordPress 3.0, and wants to start using the new menu navigation, here's how you would incorporate it into your child theme. I also wrote about this on my site: http://wordpresstheming.com/2010/03/using-3-0-menu-navigation-with-thematic/
function remove_thematic_actions() {
remove_action('thematic_header','thematic_access',9);
}
add_action('init','remove_thematic_actions');
if ( function_exists( 'add_theme_support' ) ) {
// This theme uses wp_nav_menu()
add_theme_support( 'nav-menus' );
}
function childtheme_menu() { ?>
<div id="access">
<div class="skip-link"><a href="#content" title="<?php _e('Skip navigation to the content', 'thematic'); ?>">
<?php _e('Skip to content', 'thematic'); ?></a></div>
<?php wp_nav_menu( 'sort_column=menu_order&container_class=menu&menu_class=sf-menu' ); ?>
</div>
<!-- #access -->
<?php }
add_action('thematic_header','childtheme_menu',9);
