I think hashirama can summon the bijuu....the edo madara did try to summon the kyuubi n that's when the kyuubi agreed with naruto to help him instead of being controlled by madara
hashirama clearly has enough strength(chakra) n experience to control a bijuu...it may not be kyuubi all the time but surely if madara could do it, then it's a probability that he can do it too..............xd
this way it can be explained how he once had all the bijuu (anyways it's just a theory of mine)..............xd
