You can extend Modernizr with custom tests. Just drop this at the end of your Modernizr file:

Modernizr.addTest('formdata', ('FormData' in window));

I was looking for a way to upgrade the Modernizer FormDatathe other day and could not find it.

However, this is easy to do without the Upgrade:

window.FormData // exists if it exists, undefined if it doesn't!

So:

yepnope({  
  test : "FormData" in window,
  yep  : 'normal.js',  
  nope : 'flashupload.js'  
});
