Newest Intel processors using 45nm technology have non-zero Extended
Model numbers, and therefore are not properly identified.  Currently,
this affects the Intel Atom (Ext Model 0x01, Model 0x0c), Core i7 (Ext
Model 0x01, Model 0x0A), and Xeon MP (Ext Model 0x01, Model 0x0D).
Boot a Core i7 machine and observe

Cannot bind to target CPU.  Output may not accurately describe the target.
Run as root to allow binding.
