The Internet Explorer recognizes pointer events: none, but only for SVG elements because pointer-events are only specified for SVG elements in the W3C specification (http://www.w3.org/TR/SVG/interact.html#PointerEventsProperty).
You can try it with something like this…
CSS:
#tryToClickMe{
pointer-events: none;
width: 400px;
height: 400px;
background-color: red;
}
HTML:
<svg id="tryToClickMe"></svg>
This works in IE9 and IE10 (I tested it). If you are not yet using SVG elements, then there is the posibility to wrap your existing elements in a SVG. The jQuery library provides a wrap method for that (http://api.jquery.com/wrap/).
There is a very good German article that has broken down the characteristics of the pointer events property: http://www.bennyn.de/programmierung/html/unterschiedliche-implementierungen-der-eigenschaft-pointer-events.html – There you will find (with the help of Google Translate) more information.
Hope I could help

P.S. If you want to access overlying and underlying objects, then you can use the document.msElementsFromPoint method in IE (http://msdn.microsoft.com/de-DE/library/windows/apps/hh465811.aspx). It will give you all layers on a given point in an array.
