Anytime a new device is launched the devs and the people want a couple of things. They want source code, which we have. They want root, which we now have and they want ROMs, which are soon to follow. Thanks to some great investigative work by XDA member death2all110 , rooting your device is as easy as using SuperOneClick 2.2.
Well, almost as easy anyways. You will want to check out his thread and read through the steps to get your Kindle Fire rooted. You will first need to get ADB up and running before you can proceed to root your device. That is pretty easy to do if you can read. Which I assume you can since you are reading this. So, what are you waiting for? Go check out the thread and get yourself set up. We should start seeing slimmed down ROMs and AOSP styles landing shortly.
