just to do a test because you know you can flash it back to stock 2.1, you should put the leaked 2.2 on your droid x to see if how loud it goes is more in line with what you are expecting. I dont think it will be any louder then it is on the 2.2 leak so you will know if that is loud enough for you.
Good idea ive never done the leak on android just on blackberry back in the day. Hope I dont mess the phone up or get my hand smacked by motorola..lol
