username to [author] availability

Hi! Thank you for your stunning module. I have slight problem as I convert username to full name in my template.php. Therefor everywhere in my site the full name appears.

in template.php

function phptemplate_username($object, $link = TRUE) {
if ( $object->uid ) {
$type = "profile";
  $sql = "SELECT nid FROM {node} WHERE uid = %d AND type = '%s'";
  $nid = db_result(db_query($sql, $object->uid, $type));
   if ( $nid ) {
   $profile = node_load($nid);
  }
}
$name = $profile->field_name[0]['value'] . ' ' . $profile->field_lastname[0]['value'] ;
if ( $name ) { 
    if ( $link && user_access('access user profiles')) {
      return l($name, 'user/'. $object->uid, array('title' => t('View Member Profile.')));
    }
    else {
      return check_plain($name);
    }
}

In Activity the full name appears from my username with [author] on node and comment activity, but unfortunately not with Facebook Status.

Is there a possibility of having the full name appear on Facebook Status as well please?

Look forward to any reply.
