Actually he is right. You have to know the ACPI object in order to run the _GTM/_STM etc functions. If you don't run those your suspend/resume may not work, may corrupt and so on. The only safe alternative is to disable acpi which, while it would have been a good idea before the spec ever got out, is a bit late now. If you don't run the resume methods your disk subsystem status after a resume is simply undefined and unsafe.
