a rocker board will definitely help out in powder, many of the rocker/hybrid camber boards will also allow you to go with a smaller size, I'm 5'7 145lbs and ride a 151 NeverSummer Evo, and I'm amazed at how well it rides in powder.
If you find your nose is diving, you can also use a stance setback which will put more weight in the back-seat and raise your front. A 1-2 inch setback should be enough.
