I've had to make some modifications to get the member and private scripts to display properly:

global $vbulletin;

if (THIS_SCRIPT == 'private')
{
	$tempuser=fetch_userinfo($pm['fromuserid']);
	$tempuser['permissions'] = cache_permissions($tempuser);
	$check_ugp = convert_bits_to_array($tempuser['permissions']['ces_parser_permissions'], $vbulletin->bf_ugp['ces_parser_permissions']);
}
elseif (THIS_SCRIPT != 'member')
{
	global $newpost, $postinfo, $post;

	// newthread, newreply uses $newpost
	// editpost uses $postinfo
	// showthread uses $post

	$postusername = '';

	if (THIS_SCRIPT == 'editpost')
	{
		$postusername = $postinfo['username'];
	}

	if (in_array(THIS_SCRIPT, array('newreply', 'newthread')))
	{
		$post = $newpost;

		if ($post['username'] AND ($vbulletin->userinfo['username'] != $post['username']))
		{
			$postusername = $post['username'];
		}
	}

	if (!$post['usergroupid'] AND $postusername != '')
	{
		$userinfo = $vbulletin->db->query_first("
			SELECT userid, usergroupid, membergroupids 
			FROM " . TABLE_PREFIX . "user
			WHERE username = '" . $vbulletin->db->escape_string($postusername) . "'
		");

		if (empty($post['permissions']))
		{
			$grab = true;
		}
		else
		{
			$userinfo['permissions'] = $post['permissions'];
		}
	}
	else if (($post['usergroupid'] > 0))
	{
		$userinfo['userid'] = $post['userid'];
		$userinfo['usergroupid'] = $post['usergroupid'];
		$userinfo['membergroupids'] = $post['membergroupids'];

		if (empty($post['permissions']))
		{
			$grab = true;
		}
		else
		{
			$userinfo['permissions'] = $post['permissions'];
		}
	}
	else if (in_array(THIS_SCRIPT, array('newreply', 'newthread')))
	{
		$userinfo['userid'] = $vbulletin->userinfo['userid'];
		$userinfo['usergroupid'] = $vbulletin->userinfo['usergroupid'];
		$userinfo['membergroupids'] = $vbulletin->userinfo['membergroupids'];

		if (empty($vbulletin->userinfo['permissions']))
		{
			$grab = true;
		}
		else if (empty($userinfo['permissions']))
		{
			$userinfo['permissions'] = $vbulletin->userinfo['permissions'];
		}
	}

	if ($grab)
	{
		$userinfo['permissions'] = cache_permissions($userinfo);
	}


	if ($this->parse_userinfo['permissions'] != $userinfo['permissions'])
	{
		$this->set_parse_userinfo($userinfo, $userinfo['permissions']);
	}

	$check_ugp = convert_bits_to_array($this->parse_userinfo['permissions']['ces_parser_permissions'], $vbulletin->bf_ugp['ces_parser_permissions']);
} else {
	$tempuser=fetch_userinfo($vbulletin->GPC['userid']);
	$tempuser['permissions'] = cache_permissions($tempuser);
	$check_ugp = convert_bits_to_array($tempuser['permissions']['ces_parser_permissions'], $vbulletin->bf_ugp['ces_parser_permissions']);
}
$bad_tags = explode(',', $vbulletin->options['bad_tags']);

$dobbcode = $do_bbcode ? $do_bbcode : $dobbcode;
$dosmilies = $do_smilies ? $do_smilies : $dosmilies;
$dobbimagecode = $do_smilies ? $do_bbimagecode : $dobbimagecode;
$dohtml = $do_html ? $do_html : $dohtml;

$dobbcode = ($check_ugp['can_bbcode_post'] AND $dobbcode);
$dosmilies = ($check_ugp['can_smilies_post'] AND $dosmilies);
$dobbimagecode = ($check_ugp['can_imgcode_post'] AND $dobbimagecode);

$do_bbcode =& $dobbcode;
$do_smilies =& $dosmilies;
$do_bbimagecode =& $dobbimagecode;
$do_html =& $dohtml;

if ($check_ugp['can_html_post'] AND $do_html)
{
	$do_html = true;
	foreach ($bad_tags AS $badtag)
	{
		$badtag = html_entity_decode($badtag);
		$text = str_replace( '<' . trim($badtag), htmlspecialchars('<' . trim($badtag)), $text);
		$text = str_replace( '</' . trim($badtag), htmlspecialchars('</' . trim($badtag)), $text);
	}
	unset($badtag, $badtags);
}
else
{
	$do_html = false;
}

I'm not sure that this is entirely correct, but it's a start for me.
