Same issue here. I simplified the code near the top of wp-content/themes/atahualpa351/functions/bfa_subscribe.php by trial and error. The following may not be approved, but it seems to work OK in Firefox. In IE, though, the icons appear at the left side of the footer instead of in the right sidebar. (Sorry - couldn't find in the FAQ instructions for posting code more neatly. Will repost if some says how it should be done.)
<form class="feedburner-email-form"
<table class="subscribe" cellpadding="0" cellspacing="0" border="0"><tr>
<td class="email-text" colspan="2"><p>
<a href="http://<?php echo $window_url . $id; ?>&loc=<?php echo get_locale() .
($bfa_ata_nofollow == "Yes" ? ' rel="nofollow"' : ''); ?>">
<img src="<?php echo get_bloginfo('template_directory'); ?>/images/email-feed-small.gif" style="float:left; padding:0px 10px; margin: 0 0px 0px 0" alt="" /></a><?php echo $email_text; ?></p>
<a href="<?php echo get_bloginfo('rss2_url'); ?>"<?php if ($bfa_ata_nofollow == "Yes") { ?> rel="nofollow"<?php } ?>>
<img src="<?php echo get_bloginfo('template_directory'); ?>/images/rss.png" style="float:left; padding:0px 10px; margin: 0 0px 0px 0" alt="" /></a><?php echo $posts_text; ?></p>
</td>
</tr>
</table>
</form>
Looks like this:

The smaller images were already in the same folder; just needed to change pointers (if that's the right word).
