Rails - Mar 2009 - atom_builder and link element

I''m using the atom builder to build a feed. It''s mostly
working but
the value in the link element of each entry is not being generated as
it needs to be.

My url scheme looks like http://example.com/blog/nickname/id

I have a controller called blog_entries and a routes.rb file which a
seet of maps for blog_entries, it looks something like this (amongst
all the other routes):

map.blog_entries ''blog/:nickname'',
            :controller => "blog_entries",
            :action => "index",
            :conditions => {:method => :get}
map.formatted_blog_entries ''blog/:nickname.:format'',
            :controller => "blog_entries",
            :action => "index",
            :conditions => {:method => :get}

In my views, to generate the correct URLs for links I do something
like:

<%= link_to ''New Entry'', new_blog_entry_path(:nickname
=>
@blog.nickname) %>

and this creates the correct path.

The builder code looks like:

feed.entry(post) do |entry|
  entry.title post.title
  etc...
end

The problem is the generated link in the atom output, it looks like

<link type=''....''
href="http://example.com/blog/1" />

when what I need is

<link type=''....''
href="http://example.com/blog/nickname/1" />

I''ve tried

entry.link :href => "some other url"

but that adds a second link entry into the output which is in the
wrong place in the XML so is ignored by readers.

So, can I hook into the url generation mechanism to get the nickname
value into the URL, or
can I tell the builder to use "nickname" when generating the url?

If not I guess the other thing is to generate the atom feed myself,
seems a shame not to use the builder though.
