class CGI
     def query_params
         params = {}

         ENV['QUERY_STRING'].split("&").each { |p|
             k, v = p.split("=")
             params[CGI.unescape(k)] = CGI.unescape(v)
         }

         params
     end
end

...that does the trick. God, I love Ruby. May I never stray back into 
PHP-land again :)
