Hi Andre,

This looks good to me and also thanks Martin Schiller for testing.

I would like to merge this in the next days. I do not have an ADSL line 
or a working Danube board here, did anyone tried this on Danube or 
Amazon SE? The changes are looking ok and we can wait for people to 
complain. ;-)

@Jow and @Rosen: are the changes in the feed ok? I would also like to 
merge them in parallel?

Hauke
