I understand the min-height problem has been fixed in ie7, so your hacks for that should be in a stylesheet with:
<!--[if lte IE 6]>
<link rel="stylesheet" href="IEbugs.css" type="text/css" />
According to the conditional comment this is Internet Explorer lower or equal to IE6
<![endif]-->
If you are using other hacks for IE7 you may want to put them in another stylesheet with a conditional comment for that particular version of IE.
