Now omniscience is a tricky beast and it tends to get out of hand. One might think that omniscience implies knowledge of how to do anything desired, so now there is omnipotence as well. Omnipresence is widely assumed for the Buddha. So you can see, there is some danger of assigning the Buddha the three fundamental properties of the Judeo Christian God at which point they become difficult to distinguish.
So I think the whole question can be rephrased as, "What are the actual limitations on a Buddha's omnipotence?" If there aren't any, don't we just have Christianity with the names translated into Asian languages?
The Buddha's function and omniscience is entirely different from monothestic conceptions, because the underlying worldviews are fundamentally different. Christianity operates under the worldview that there is a Creator and he is omnipotent and created all. Buddhism operates under the worldview that there is no creator, all of samsara arose due to ignorance and dependent origination, Buddhas are liberated and their unceasing function is to teach others to free themselves. So its apples and origami.
