Help for show different forumdisplay templates

[nando.dominios]

I put this for test a idea in forumdisplay but raw forumdisplay_mod not work(i have a forumdisplay_mod template created):

<vb:if condition="$bbuserinfo[userid] == 1"> 
     {vb:raw FORUMDISPLAY_MOD}
<vb:else />
     Original template code here.
</vb:if>

My idea is show alternative forumdisplay template in a especific forum id, the condition bbuserinfo=1 is only for test purposes which admin user.
