Would the tech docs on this sensor be helpful?  I found them on the Intel
site.  It describes all the registers in detail.

See Chapter 23.
http://www.intel.com/Assets/PDF/datasheet/319973.pdf

Let me know if I can do any debugging or coding to help out.  I'm proficient
in C and C++.  Just don't understand how all this sensor stuff works ;)
