http://www.magentocommerce.com/knowledge-base/entry/adding-page-links-in-the-navigation-bar 

starting magento ce 1.7 there event lets add top menu.
event page_block_html_topmenu_gethtml_before. in default theme, used add categories in menu. check out method mage_catalog_model_observer::addcatalogtotopmenuitems(). can same.
if working on versions before 1.7 edit file app/design/frontend/{interface}/{theme}/template/catalog/navigation/top.phtml , add link inside ul element:

<ul id="nav">     <?php echo $_menu ?>     <li><a href="<?php echo $this->geturl('', array('_direct'=>'page_identifier_here'))?>"><?php echo $this->__('text here')?></a></li> </ul> 

or this

<ul id="nav">     <?php echo $_menu ?>     <li><a href="<?php echo $this->geturl('page_identifier_here')?>"><?php echo $this->__('text here')?></a></li> </ul> 

the approach version 1.6 works in 1.7 it's not clean.
