This patch isn't a fix, though, it's merely adding some new stuff from a new release of the IORT spec. Either way, since I discovered we do actually have approval to contribute to ACPICA directly, I now intend to route the header change that way per Rafaels' preference[1] - patch 2/2 will take care of itself in the meantime.
