This is really braindamage inflicted by microsoft with the StorageD3
property on ACPI systems.  It is in general a really, really bad idea
as it saves a little power but massively wears out the flash.  It seems
like Chromebooks and DT just want to keep up with the Jones.

Which is a reminder that we should probably integrate the StorageD3
handling into this framework.
