um, thats stupid, I figured the PWM models would be based on 5V as there is only need for a pulsed signal not a voltage.. oh well.

Ron, what about using a 10V power supply to power the arduino, and then taking the power from your 9V out wich will actualy be 10V. this will eliminate that need of another power supply as I can't imagin you need much of any current for the PWM.
