This version seems to be implemented entirely in WMI, and it's using the
same WMI GUID as asus-wmi - implementing it here seems appropriate. I am
concerned about the phys/virt thing, though. The ACPI interpreter is
running in the kernel, not the hardware - are we artificially limiting
SystemMemory opregions to physical addresses?
