I think froumhome does not have an associated forumid, so if you want them to show in forumhome, maybe try this:

global $show, $forumid;
if (!isset($forumid) OR !in_array($forumid, array(1, 2, 3)))
{
   $show['ads_forumid_variable'] = 1;
}

I'm not sure why it wouldn't work in postbit_legacy. What did you have in that template before?
