Has probado cargando el flash con javascript, utilizando SWFObject
<script type="text/javascript">
var so = new SWFObject("movie.swf", "mymovie", "200", "100%", "8", "#336699");
so.addParam("quality", "low");
so.addParam("wmode", "transparent");
so.addParam("salign", "t");
so.write("flashcontent");
</script>
Aquí tienes el javascript
