HTML5 issue on IE with ajax callback

When loading content through ajax in Internet Explorer, the new html5 elements are not recognized / processed with the html5shiv thingie.

I've used innershiv to mitigate my issue, with the following example code. Maybe this is usefull for omega?
(btw, I've peeked into zen theme and borrowed their solution ;))

in html.tpl.php:

    <!--[if lt IE 9]><script src="http://html5shiv.googlecode.com/svn/trunk/html5.js"></script>
  <script src="/path/to/theme/js/innershiv.js"></script>
  <script type="text/javascript">
// Monkeypatch the innerShiv in the ajax insert method.
 (function(){if(Drupal.ajax){var _insert=Drupal.ajax.prototype.commands.insert;Drupal.ajax.prototype.commands.insert=function(ajax,response,status){response.data=innerShiv(response.data,false);_insert(ajax,response,status);}}})();
</script>
