The ACPI 1.0 spec is followed by windows XP. And the power state is not
checked in power transition under windows XP.
But we don't know whether it is still skipped on the new version
windows.(For example: Windows 7).

If the module param is removed, we must delete the source code related
with power state check. And if the power state is checked in power
transition on windows 7, what we should do? It is not reasonable to add
them again.

Maybe it is better to determine whether the power state check is skipped
in power transition.

Thanks.
