Older versions of IE don't support multiple background images, so they ignore attempts to use them - which can cause those browsers to ignore previous valid settings. You need to use conditionals to override or supplement your CSS3 background settings, as in:

<!--[if lt IE 9]>
<style type="text/css">
#myDiv { background: url("image.png"); }
</style>
<![endif]-->
