Replace the normal posts rss feeds with pages feed. For WordPress 3+ use http://wordpress.org/extend/plugins/rss-pages-for-wordpress-v3/
One problem with WordPress is that the RSS feed only contains the latests posts and not pages. The idea I suppose is to have a feed which the blogosphere can use to know when there is updated news on your site. That's ok for most WordPress sites but when you are using as WordPress as a CMS and thus using pages and not posts you can't put the pages into a feed.
For WordPress v3+ please use http://wordpress.org/extend/plugins/rss-pages-for-wordpress-v3/
Note: This plugin replace your posts feed with page feeds.
