You're begging the question by assuming an omnipotent god is not powerful enough to allow a contradiction to exist. Your argument relies on a contradiction implying that the situation is impossible, and therefore omnipotent god can't do it, and that would imply he is not omnipotent. But, if he's omnipotent, he can make something both true and false at the same time (otherwise, he wouldn't be omnipotent, it would be a contradiction :D ). So he can both create a rock he can't lift and lift it, simultaneously. In other words, the existence of an omnipotent god implies the possibility of p and not p for all p. Duh.
