I have searched for the answer to this, but I can't find it anywhere. I'm currently trying to alter the super slam perk to only work on two-handed melee weapons while power attacking. I see how to alter what type of weapons a perk effects, but I cannot see a conditional for power attacks. Anyone able to help me out here? Just to clarify, I can't find what "condition function" will return whether my character is power attacking, if one exists at all.

I'd like to know as well. Im in the process of giving dynamic knockdown/out chances for melee and unarmed (pitting player skill & stats v enemy skill & stats) and i might use it too, though it'll more likely be done thru script. Like the OP i was unsatisfied with how weapons that shouldnt have the same knockdown power were nevertheless given the same chance of knocking down. a 10 STR 100 melee player should not have the same chance to knockdown an enemy as a 4 STR 40 Melee player vs an END 10 or END 1 enemy dammit!
