Try the following instead:

    function FeedText($pagename, &$page, $tag) {
        $text = RetrieveAuthSection($pagename, '##blogend');
        $content = MarkupToHTML($pagename, $text);
        return "<$tag><![CDATA[$content]]></$tag>";
    }

The '##blogend' argument says to read from the beginning of the page
to just before the line containing the [[#blogend]] marker.  See
http://www.pmwiki.org/wiki/PmWiki/IncludeOtherPages for more information
about the section specifications.

This version won't read text from pages that are read-protected;
if you want to get text even from read-protected pages, then 

        $text = RetrieveAuthSection($pagename, '##blogend', NULL, 'ALWAYS');

Hope this helps!
