support. These registers are enabled in the PCI Device 31: Function 0 space
(PM_IO_EN), and can be moved to any I/O location (128-byte aligned). The registers
are defined to support the ACPI 2.0 specification, and use the same bit names.
All reserved bits and registers will always return 0 when read, and will have no effect
when written.
