The diff below fixes an issue with the way we attach "APCI devices".
As with all ACPI diffs, this may potentially introduce regressions, so
some wider testing would be welcome.
The fix itself involves resolving a "nameref" in the package that
describes dependencies between APCI devices. These namerefs need to
be evaluated lazily (for reasons) but this wasn't done in this case.
