If you go to the main Manageability page, you'll notice there's a new SDK available, the Remote Encryption Management SDK. This SDK shows how to unlock and work with vPro systems that have encrypted hard drives (those hard drives can either be software encrypted, or FDE hard drives). Note that it is intended to work with an existing software solution that already handles provisioning the hard drives for security and maintaining the hard drive access credentials, at least initially.
I'll be posting a blog on this later in the week with some more details, you can also go to the download page for the SDK to get a bit more information (http://software.intel.com/en-us/articles/download-the-latest-version-of-Remote-Encryption-ManagementSDK/), and feel free to ask any questions in the forums about this.
