Change your profile so that it doesn't auto sign you into xbox live when you turn it on. Once the xbox is on open the guide, go all the way to the right and go to preferences and set online status to offline. Then sign in and you will appear offline. You have to set yourself to appear offline again though every time you turn your 360 off and on but it only takes 10 seconds.
I know how you feel though, I do this all the time.
