Power Attack, and Breaker Rush

[DinadanC]

Hello all,

Looking at the Siegebreaker Fighter Archetype. You gain Breaker Rush.

Breaker Rush (Ex): At 1st level, a siegebreaker can attempt bull rush or overrun combat maneuvers without provoking attacks of opportunity. When he performs either combat maneuver, he deals an amount of bludgeoning damage equal to his Strength bonus (minimum 1).

I know you can Power Attack with a combat maneuver, but could you Power Attack your Bull Rush to increase your damage with this ability?

Thanks,

"You can choose to take a –1 penalty on all melee attack rolls and combat maneuver checks to gain a +2 bonus on all melee damage rolls"

"he deals an amount of bludgeoning damage equal to his Strength bonus (minimum 1)."

It looks like no offhand as you're not making any damage rolls for power attack to boost, you are just doing damage.
