Recoded my reg form and it works fine now. Can't seem to work out the login form, so I looked at your login script.

PHP Code:

 // ======== USER LOGIN / LOGOUT ========

   function login($vbuser)
   {
      global $vbulletin;
      $vbulletin->userinfo = fetch_userinfo_from_username($vbuser['username']);
      // set cookies
      vbsetcookie('userid', $vbulletin->userinfo['userid'],
         PERMANENT_COOKIE, true, true);
      vbsetcookie('password',
         md5($vbulletin->userinfo['password'].COOKIE_SALT),
         PERMANENT_COOKIE, true, true);
      // create session stuff
      process_new_login('', 1, '');
   } 


which i'm assuming is that? if so, passing as $forum->login($userdata) is not working for me, but looking through your code, I also don't know if that does work.
