I think that Kabuto was in fact messing up not with Madara's soul, but technically with his body (or rather body of the sacrifice used to reanimate him). However, I must admit that it rather fits to Hashi's implant which can be simply given that way, but I have no idea how Kabuto managed to restore Madara's body up to his prime state, complete with the EMS (despite him being an old man with one foreign Sharingan at the moment of his death).
