   9           native Intel hardware idle features.  The acpi_idle driver
  10           can be configured at the same time, in order to handle
  11           processors intel_idle does not support.

  24           Enable memory power savings when idle with certain Intel server
  25           chipsets. The chipset must have I/O AT support, such as the
  26           Intel 7300. The power savings depends on the type and quantity of
  27           DRAM devices.
