I have a custom query for my network site home page that pulls in all the recent post of the all the blogs. Wordpress realizes that I don't have post for that specific blog so after the first page all my additional pages return 404 but the query is still displayed. The root cause is the wp_class.php function handle_404 (). Does anyone have a work around that might assist with my situation. Or how do I overwrite the wp_query to use my query temporary for that page.

function get_eh_all_grp_recent_post($blog_list){
    global $wpdb;
    $other_sqlstr = '';
    $limitstr = '';
    $uni = '';

    foreach ($blog_list AS $blog) {
      if ($other_sqlstr != '')
        $uni = ' union all ';;
      if($blog['blog_id'] == 1) {
        $other_sqlstr .= $uni . " (SELECT ".$blog['blog_id']." as blog_id, id, post_date from wp_posts where wp_posts.post_status = 'publish' and wp_posts.post_type = 'post' and wp_posts.post_title <> '".__('Hello world!')."')";
      }
      else {
        $other_sqlstr .= $uni . " (SELECT ".$blog['blog_id']." as blog_id, id, post_date from wp_".$blog['blog_id']."_posts where wp_".$blog['blog_id']."_posts.post_status = 'publish' and wp_".$blog['blog_id']."_posts.post_type = 'post' and wp_".$blog['blog_id']."_posts.post_title <> '".__('Hello world!')."' )"; 
      }     
    }

      //$limit = ' LIMIT '.$start_page.', 10';
    $other_sqlstr .= " ORDER BY post_date desc ";// . $limit;

    $grp_recent_posts = $wpdb->get_results($other_sqlstr, ARRAY_A);
      //echo $wpdb->print_error();

    return $grp_recent_posts;
  }
