I don't think trying to solve it materialistically will work, because the moment we come up with an empirical measurement of consciousness, David Chalmers will crash in through a window and say "ah, now consider a hypothetical class of people for whom this measurement indicates consciousness, but who do not in fact experience qualia - we could call these qualia zombies, or Q-zombies for short."

Maybe the correct response is just to dismiss zombie theories as incoherent. But people are already doing that - I doubt collecting more physical evidence and improving our understanding of cognition will strengthen the case against P-zombies, even though it'd be useful knowledge for other reasons.
