Do the CPU Power state pins work?

I'm wondering if I am missing something on these CPU state pins (S0, S3, S4, S5). I tied them to inputs on the arduino and was getting HIGH values all the time, so I tested it with my DMM and I am seeing the same thing. As long as the LPA has power, all four pins always read high. Has anyone seen a more expected behavior from these signals?
