Blogspot sucking more

Dear Lazyweb,

Can you please tell me about a service like Feedburner or something like that, which takes my invalid ATOM feed that Blogspot guys graciously provide me with and converts it to a valid something (Atom, RSS, whatever)?

The fact that Blogspot spits moronic XML instead of a valid ATOM feed is the only thing that is taking me this long to update Planet Noori to a way better (and easier) implementation...
