^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 313)  *  March 2005:
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 314)  *  Added support for a package that contains two integers. This
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 315)  *  goes against the ACPI specification which defines this object as a

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 317)  *  by many BIOS vendors is to return a package with 2 or more integer
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 318)  *  elements, at least one per sleep type (A/B).
