I am feeling pleased with myself as I have just successfully installed the full version of Duokan on my new Kindle 3g EU version with Firmware 3.2.1.
This was a little complicated in so far as I had to trawl through some of the chinese forums to work out what to do:
Look at
http://www.duokan.com/forum/thread-24049-1-1.html Note: when I used Chrome browser the page auto loaded with the option to translate to English which was how I deciphered it!
Get the .rar file indicated in the post.
Look at Flip's site

Download the English pre-configured package. You need the DK folders from this archive.

It all proceeded just as the forum suggested.
