Splitted into 3 parts:
- - Backport ability to reset the machine using the RESET_REG of ACPI
  (Hardy/Intrepid*)
   *Applicable partially to Intrepid, the framework is there but acpi_reboot()
    does nothing and falls back to keyboard method. Commit SHA points to the
    upstream commit that added this
- - SAUCE: Add the ability to whitelist systems to use ACPI reboot
  (Hardy/Intrepid) taken from a proposal of the referenced bug report.
- - SAUCE: Add reboot=a preselection quirk
  (Hardy/Intrepid) This is optional and just selects the right method for
  reboot, adds to the code already in place for Dell.

When all other means of communication fail, try words!
