I'm with Eric, Dee. It sounds like there are a lot of time changes going on. Add in some syncopation, and you have a rhythm that ends up on the "4" every couple of bars, but would drive a drummer nuts if he didn't have any points of reference.
I think this is one of those songs where your going to have to go through it bit by bit, and show the drummer were to put in *something* (like an open hi-hat, or a cymbal) to keep everyone on the same page. With repetition, I think everyone will get it.
