I think you make a fundamental mistake when you assign so much significance to the question of the computability of brain physics, or to the question of the computability of physics in general.

Unlike observer-independent objects like mountains and planets, computations are always observer-relative. They exist only relative to the mind of some observer who does the computations. 

At the most basic level, this explains why it makes no sense to think of the brain as a computer. If the brain really equals a computer then it needs an observer/user, which leads to the homunculus fallacy.
