  I guess it now possible in Rails3.

          redefine_method("#{reflection.name.to_s.singularize}_ids=") do |new_value|
            pk_column = reflection.primary_key_column
            ids = (new_value || []).reject { |nid| nid.blank? }
            ids.map!{ |i| pk_column.type_cast(i) }
            send("#{reflection.name}=", reflection.klass.find(ids).index_by{ |r| r.id }.values_at(*ids))
          end
