I've added the following code to my config.php. It's been a while since
I looked at it and it might not be the best way to do it, but perhaps
it'll help you.

What I'd really like to add is a "more" link, but I'd really need a way
to figure out the page variable and how to add the proper code to the
entry.

// support feeds
if ($action=='rss') {
    include_once('scripts/feeds.php');

    // only do this for the 'Blog' group
    $_group = PageVar($pagename, '$Group');
    if ($_group=='Blog') {

        // set defaults for the blog group
        $_REQUEST = array(
            'group' => $_group,
            'name'  => '????-??-??[-_]*',
            'order' => '-name',
            'count' => 10
        );

        // global RSS options
        $FeedFmt['rss']['feed']['title'] = '$WikiTitle Blog';
        $FeedFmt['rss']['feed']['description'] = 'Balus Blog';

        // why is ?action=rss added by default to the link tag? 
        // Am I missing something? Anyway, remove it using:
        $FeedFmt['rss']['feed']['link'] = '{$PageUrl}';

        // Google Reader does not like text/xml? :-(
        // proper value should be application/rss+xml anyhow
        $FeedFmt['rss']['feed']['_header'] = 'Content-type: application/rss+xml; charset="$Charset"';

        // helper function that fetches the title pagetext variable for each item
        // (or the default from page BlogOverviewTemplate)
        function BlogTitle($pagename)
        {
            $PTVTitle = PageTextVar($pagename, 'Title');
            if ($PTVTitle=='') $PTVTitle = PageTextVar($_group.'/BlogOverviewTemplate', 'TitleDefault');
            $PTVTitle = strip_tags(MarkupToHTML($pagename, $PTVTitle));
            return $PTVTitle;
        }
        $FmtPV['$BlogTitle']   = 'BlogTitle($pn)';

        $FmtPV['$BlogExcerpt'] = 'htmlspecialchars(MarkupToHTML($pn, "(:include $pn#entrybody#extendedbody:)"))';

        // content of RSS items (besides default)
        $FeedFmt['rss']['item']['title']       = '$BlogTitle';
        $FeedFmt['rss']['item']['description'] = '$BlogExcerpt';

        // W3C feed validator says: an item should not include both pubDate and dc:date
        // W3C feed validator says: item should contain a guid element
        $FeedFmt['rss']['item']['dc:date']     = '';
        $FeedFmt['rss']['item']['guid']        = '<guid isPermaLink="true">{$PageUrl}</guid>'."\n";
    }
}
