  Added files:
    sys/i386/cpufreq     est.c 
  Log:
  Add the Enhanced SpeedStep driver (EST).  Currently, this driver only works
  on the previous generation of Pentium-M processors (Banias).  Support for
  Dothan and later processors involves working with acpi_perf(4) to extract
  information about supported states.  This driver should work on MP systems
  including HTT.  It is experimental and may have a few bugs but has been
  tested to not crash at least.
  
  Thanks to Colin Percival for his initial work on this driver.
