I don't think a great deal is known about these even if P and Q are only quadratic polynomials.
but this should have read:

I figured :) Also, I assumed that because Louiville's theorem involved consideration of a generalised Jacobian that cases as above were generically included in the proof ? Again I think I'm missing something obvious.
