Hi Tobia! I am happy to know that you are still working on this project!
Maybe adding a small progress comment on http://trac.helenos.org/ticket/419 mentionning both links you gave me would help people know you are still working on this.
In fact it should probably be a feature issue in https://github.com/genodelabs/genode/issues/ too.
Indeed reading http://trac.helenos.org/wiki/Genode give me an idea of the quite big challenges you are facing while clearly showing the differences between Genode and HelenOS which I find quite instructive.
I hope to find some time to follow your progress and wish you good luck!
