+ * Added support for a package that contains two integers. This
+ * goes against the ACPI specification which defines this object as a
+ * package with one encoded DWORD integer. However, existing practice
+ * by many BIOS vendors is to return a package with 2 or more integer
+ * elements, at least one per sleep type (A/B).
*
- * DESCRIPTION: Obtain the SLP_TYPa and SLP_TYPb values for the requested sleep
- * state.
+ * January 2013:
+ * Therefore, we must be prepared to accept a package with either a
+ * single integer or multiple integers.
+ *
+ * The single integer DWORD format is as follows:
+ * BYTE 0 - Value for the PM1A SLP_TYP register
+ * BYTE 1 - Value for the PM1B SLP_TYP register
+ * BYTE 2-3 - Reserved
+ *
+ * The dual integer format is as follows:
+ * Integer 0 - Value for the PM1A SLP_TYP register
+ * Integer 1 - Value for the PM1A SLP_TYP register
