The idea that free will is compatible with determinism (this position is called, shockingly, compatibilism) is actually the most popular view in the philosophical debate about free will, and has nothing to do with mind-body dualism. Some ways folks have tried to defend compatibilism (see http://plato.stanford.edu/entries/freewill/ http://plato.stanford.edu/entries/freewill/ for discussion of what follows): motivating the idea that free will is grounded on choice on the basis of one's desires, or on choice that makes sense given one's values. There are other ways, linked to the idea of it being possible that you had chosen otherwise, and on a metaphysics of modality (i.e., of what it is for something to be possible, or necessary) compatible with determinism.
