> But work such as Bell's theorem shows that no deterministic equation could ever be consistent with quantum mechanics:

This isn't quite right, because you left out the word 'local' - see http://en.wikipedia.org/wiki/Bohm_interpretation

Bell's theorem applies only to _local_ hidden variables.

Right, but non-local determinism is difficult to square with general relativity.

Indeterministic laws and the non-existence of particle positions and trajectories are difficult to square with general relativity too - and Bohm's interpretation doesn't 'suffer' those problems, while it predicts the exact same observations. (Though I should say this is way out of my amateur-physicist league - I'm taking my cue from 'Quantum Mechanics: Historical Contingency and the Copenhagen Hegemony' http://www.amazon.com/Quantum-Mechanics-Historical-Contingen... ).
