I wonder if there is the possibilaty to load some javascript files only if its not the IE 8 like this:
<!--[if NOT IE 8]>
<script type="text/javascript" src="assets/scripts/slideshow.js"></script>
<![endif]-->
<!--[if IE 8]>
<script type="text/javascript" src="assets/scripts/slideshowOnlyForIE8.js"></script>
<![endif]-->
Try this (cited from here)…
