Here is a whitepaper about how to define a new proof of work system that gives preference to CPU's forever theoretically and is immune to vulnerabilities that encryption algorithms are prone to.

The take home message is to find a single factor (of a length defined by the difficulty) of a very large number (over 100 digits).

Since it is such a large number GPU's become very slow at attempting it by themselves.

It appear this PoW would be the perfect marriage of GPU and CPU as a GPU seems to speed up the first part (the easiest part) of the factorization:
