Recent Posts code

Hello!

Does anyone know how I can get the following code to work for 3.0 MU? My sub-domain sites will NOT have their own blogs, but I would like all of them to display recent posts from the root domain:

<ul>
                    <?php
                      $number_recents_posts = 6;//Can be how much you want
                      $recent_posts = wp_get_recent_posts( $number_recents_posts );
                      foreach($recent_posts as $post){
                        echo '<li><a href="' . get_permalink($post["ID"]) . '" title="Look '.$post["post_title"].'" >' .   $post["post_title"].'</a><br /><div class="newsdate">Posted: '.$post["post_date"].'</div></li> ';
                      } ?>
                    </ul>
