OK I had the same problem so I started the bounty, but after that I found the working solution (for me at least):
(where myapp is really your app name)
So to recap, here is my IE7/8/9 working HTML page:
<!DOCTYPE html>
<html lang="en" class="ng-app:myapp" id="ng-app" ng-app="myapp" xmlns:ng="http://angularjs.org">
<head>
<!--[if lt IE 9]>
<script src="http://html5shim.googlecode.com/svn/trunk/html5.js"></script>
<![endif]-->
<!--[if lte IE 8]>
<script>
document.createElement('ng-include');
document.createElement('ng-pluralize');
document.createElement('ng-view');
document.createElement('ng:include');
document.createElement('ng:pluralize');
document.createElement('ng:view');
</script>
<![endif]-->
<!--[if lt IE 8]>
<script src="js/json2.js"></script>
<![endif]-->
</head>
<body>
<div ng-view></div>
</body>
</html>
