Oh I forogt a little detail,.. =)
It was clear to me that I get new selfsigs on the primarykey/userid when 
changin settings (like prefered algorithms, etc.) and it is also clear 
to me that the older selfsigs will return from the keyserver (but they 
should be ignored by other users due to the older creation time).

Was I wanted to know was: How can I get new subkey binding sigs for my 
subkey (new: with more recent creation time, and of course with the 
"better" hash algorithm)?

It would be better to wait with doing this until gpg understands 
backsigs, right?

btw: Do encryption keys get backsigs, too? If not why not?

Best wishes,
