I had the same idea but implemented it differently, without the added table field:

Open search.php and find:

PHP Code:

// ###################### Start get new #######################
if ($action=="getnew") {
  // generate query
  // do it!
  if ($bbuserinfo[userid]!=0 or $bbuserinfo[lastvisit]!=0) {
    $forumsql=getallforumsql(); 


After that, add:

PHP Code:

// HACK: search for normal or usenet posts
            if ($usenet=="true") {
                  $forums=$DB_site->query("SELECT forum FROM nntp_groups");
                  $forumsql.=" AND forumid IN (0";
                  while ($forum=$DB_site->fetch_array($forums)) {
                      $forumsql.=",$forum[forum]";
              }
            $forumsql.=")";
            } else {
                 $forums=$DB_site->query("SELECT forum FROM nntp_groups");
                  $forumsql.=" AND forumid NOT IN (0";
                  while ($forum=$DB_site->fetch_array($forums)) {
                      $forumsql.=",$forum[forum]";
                  }
                  $forumsql.=")";
        }
// HACK: search for normal or usenet posts 


Then update your forumhome_newposts template to include 2 links rather than one:

To look for normal posts:
<a href="search.php?s=$session[sessionhash]&action=getnew&usenet=false">

To look for usenet posts:
<a href="search.php?s=$session[sessionhash]&action=getnew&usenet=true">

Not being a PHP wizard I am not 100% sure that this would cover all angles but it seems to work for me fine so far
