It didnt work here either.. Anyway try hacking:
Edit index.php, find:

eval("\$forumbits .= \"".gettemplate("forumhome_forumbit_level$depth$te mpext")."\";");

Replace it as

if ($forum[forumid]!=54) {
eval("\$forumbits .= \"".gettemplate("forumhome_forumbit_level$depth$te mpext")."\";");}
else {
eval("\$forumbits .= \"".gettemplate("forumhome_forumbit_54")."\";") ;}

Then create template named "forumhome_forumbit_54" and put any content there.
