title: Modernizr.load not working properly in IE8
body: <p>I'm trying to load in a specific CSS stylesheet depending whether certain CSS3 features aren't supported in that browser.</p>
  
  <p>The JS code I use is this:</p>
  
  <pre><code>// Modernizr feature tests
  Modernizr.load({
      test: Modernizr.borderradius,
      nope: '/assets/css/border-radius.css'
  });
  </code></pre>
  
  <p>In IE8 this gives, according to the developer tools:</p>
  
  <pre><code>&lt;link href="undefined" rel="stylesheet" type="text/css" /&gt;
  </code></pre>
  
  <p>Any ideas?</p>
