One difficulty with implementing this is that there are lots of different polynomial classes, and also lots of different __pow__ methods. In each case one could perhaps test to see of the characteristic was p>0 and the exponent a power of p, and call special code. (I think this was done a while ago for powering elements of finite fields.)
In the case of univariate polynomials over GF(p) the type of the polynomial is 'sage.rings.polynomial.polynomial_zmod_flint.Polynomial_zmod_flint' which suggests to me that the powering is done within the Flint library. In which case that is where improvements should be made (in this case).
