This Mod is working perfect on my S3 Stock ICS.
I used to have a clumsy semi effective workaround with Tasker using macros to imitate button pushes. I abandoned that long ago. But this mod works great. Now Tasker can easily disable/enable Location preference at screen off/on without that daft popup consent notification.
