I'm confused why you need ACPI at all.  The TPM code doesn't require
ACPI (I wish it did but Alan Cox Nak'd that patch).  I don't see acpi
anywhere in the ima code.  What's the problem we are solving?  Why
does IMA care about ACPI at all?  And aren't you really just dropping
the build requirement on TCG_TPM?  Is that a great idea?
