Here's a hook that works for us for anyone that's interested:
// IE mac hangs when there are several icons to be loaded
function _prefs_hook_show_icons()
{
    $browser =& Browser::singleton();
    if ($browser->getPlatform() == 'mac' && $browser->getBrowser() == 'msie') {
        return false;
    }
    else {
        return true;
    }
}
