Just in case anyone was wondering, here is a version of the toggle1x script that works with 23081. I modified some stuff and it works with my standard version great! I don't have it in cab form, but if you install the original cab, just replace the script file in Program Files with mine! Let me know if it works or not for you.
I have been getting a lot better battery life out of the ROM with this installed and the switch between the modes is pretty quick.
Here is the original cab thread:
