DFRobot shield + PWM modes? 9-bit, 10-bit, phase-correct, pre-scaler 1?

I have the DFRobot 2A motor shield (product code: DRI0009) and would like to use it with Arduino Uno R3.  Can this shield work with 9-bit, or 10-bit phase-correct PWM mode with the pre-scaler set to 1?  I need more PWM duty-cycle resolution as well as frequency.

2012-08-08 23:03:59 It is surly that you can use motor shield with various PWM frequency. As every motor has its only best match PWM frequency. We have several motors which need higher PWM output. There is no damage to the motor. Just give a try and good luck. userHeadPic R2D2C3PO

And I already know how to adjust the Atmega32 registers and stuff to make this work (I've read that article before, and many, many more :) ).  I was just asking to find out whether there are any known negative side-effects when using this shield with different PWM modes.

Anyway, I'll try it out and post my results here.

2012-08-07 14:23:07 You need to adjust PWM frequency in this case.  The default PWM cycle is 500us.
