I don't see the point. Just add a custom HTML mod and paste in the HTML feedburner gives you (I turn off my editor in the Control panel first). That way you don't have to disable to creator's credit or figure out your ffid or even download and install anything. So what is easier?

Was struggling with the Joomla layout which was not working for me. This is much much nicer. Only thing I encountered was that when I turned on linkable title and when I click on the link it brings me to the Joomla layout again. Perhaps I need to play with it a bit further...
