Looks fine to me.
One question - is it expected that matching ACPI data nodes is always case insensitive?
That would not be a correct expectation in theory, although I don't think it really matters in practice.
From my reading of the Hierarchical Data Extension and ACPI Spec, I thought that was the case (section 19.3.1 ASL Names - ASL names are not case-sensitive and will be converted to upper case).
Section 19.3.1 is applicable to object names and not to the data returned by those objects. The link names in the Hierarchical Data Extension are data returned by _DSD (or other objects related to it). They are general ACPI strings and those are case-sensitive.
Thanks, Rafael
