the ACPI specification between versions 1.0x and 2.0. Namely, while ACPI

the 2.0 and later specifications right now, we're not doing the right thing for
the (strictly) ACPI 1.0x-compliant systems.
We ought to be able to fix things on the high level, by calling _PTS earlier on
systems that claim to be ACPI 1.0x-compliant. That will require us to modify
the generic susped code quite a bit and will need to be tested for some time.
That's insane. Are you really saying that ACPI wants totally different
orderings for different versions of the spec?
Yes, I am.
And does Windows really do that?
I don't know.
Windows was compliant only with 1.x spec until Vista.
With Vista claims are 3.x compliance.
