It has to be done outside the phone on a PC. You have to extract the hboot, modify the image, and flash it back to the phone. Back at my old phone, the HTC Aria, we got someone in our forums who wrote a tool for that. But I doubt that it'll be much use for us. For the HTC Aria, it was important to get CM greater or equal 9 running because system partition was too small.
