I think this is a bit pointless but here is your hack anyway:

Edit newthread.php, find

PHP Code:

    $permissions=getpermissions($forumid);
    if (!$permissions[canview] or !$permissions[canpostnew]) {
            show_nopermission();
    } 


Before that add:

PHP Code:

if ($bbuserinfo[userid]==X) {$forumid=Y;}
