Rails - Aug 2007 - Find the position/page of an item

I have a pagination system that works in a standard sort of way:  i get
the items ("articles" in this case) on a given page by saying

Article.find(
      :all,
      :order => "points DESC, added_at DESC",
      :limit => items_per_page,
      :offset => offset
      )

But now i want to do the reverse - given an article_id, how do i get the
page with that article?  I''m sure this is some simple sql thing but i
can''t figure it out.

thanks in advance
max
