Help needed to fix wp feeds keeping a plugin and action hook working

  • Hi,
    We’re running a very big blog under wp 2.9.2 with a custom plugin that generates a custom feed, needed to show the latest posts on a ruby-on-rails website.
    The plugin has been provided by other developers and it requires feedburner feeds to be specified in the <head> section of the header.php template.
    we’re not able to hack it because we don’t have access to the ruby-on-rails website to find another way to feed it bypassing feedburner, that is required to make everything work.
    The result is that the default wordpress feeds are not working so I’d need your help to have them back.

    In the wp root folder we have this wp-sw.php file:

    <?php
if (empty($wp)) {
	require_once('./wp-config.php');
	wp('feed=rss2');
}
require (ABSPATH . WPINC . '/feed-sw.php');
?>

    Then we have a feed-sw.php file in the wp-include folder:

    <?php
header('Content-Type: text/xml; charset=' . get_option('blog_charset'), true);
$more = 1;

?>
<?php echo '<?xml version="1.0" encoding="'.get_option('blog_charset').'"?'.'>'; ?>

<!-- generator="wordpress/<?php //bloginfo_rss('version') ?>" -->

    We don’t understand how they interact with this plugin, that genereates the feed that is used by the ruby-on-rails website:

    <?php
/*
Plugin Name: Export Feed
Version: 1.0.0
*/

function wonys_export_feed($comment) {
header('Content-Type: text/xml; charset=' . get_option('blog_charset'), true);
$more = 1;

?>
<?php echo '<?xml version="1.0" encoding="'.get_option('blog_charset').'"?'.'>'; ?>

                        if (($values[0] == '') || ($values[0] == null) || ($values == null)) {
                            	echo("featured.png");
                        } else {
                            echo $values[0];
                        } ?></image>
		<wfw:commentRss><?php echo get_post_comments_feed_link(); ?></wfw:commentRss>
<?php rss_enclosure(); ?>
	<?php do_action('rss2_item'); ?>
	</item>
	<?php endwhile; ?>
</channel>
</rss>
<?php
}
function wonys_add_feed() {
  add_feed('sw', 'wonys_export_feed');
}
add_action('init','wonys_add_feed');
?>

    I would have used a normal xslt transformation or another way to feed the website, but we cannot edit this at the moment.
    So, what piece of code could be the one that breaks the default wp feeds?

    I know this may be a difficult question with very few information, but if you need any other detail to help me just let me know ??

    Thank you in advance!
