  Log:
  Identify the Deerfield processor. Deerfield is a low-voltage variant
  based on the Madison core and targeting the low end of the spectrum.
  Its clock frequency is 1Ghz, whereas Madison starts at 1.3Ghz. Since
  the CPUID information is the same for Madison and Deerfield, we use
  the clock frequency to identify the processor.
  Supposedly the Deerfield only uses 62W, which seems to be less than
  modern Xeon processors (about 70W) and about half what a Madison would
  need.
