The Most Popular Search Engines in Norway [webmasterworld.com] answers your question perfectly.
You could check the this thread [webmasterworld.com] out, where Tor mentions that Kvasir got 347 mill. queries in 2002 just to get a "feeling" of the market.
Then there's The Great Scandinavian Survey [webmasterworld.com] with even more numbers from our Scandinavian members.
Good luck! :)
