  Dynamically choose the quality of the ACPI timer depending on whether
  the fast or safe/slow method is in use.  Fast remains at 1000, slow is
  now at 850 (always preferred to TSC).  Since the HPET has proven slower
  than ACPI-fast on some systems, drop its quality to 900.  In the future,
  it is hoped that HPET performance will improve as it is the main
  timer Intel supports.  HPET may move back to 2000 in -current once RELENG_7
  is branched to ensure that it gets tested.
