This shouldn't actually be set on IA64, should it? IA64 doesn't have BIOS, either, it has EFI/UEFI, like ARM64...
Which ACPI tables are in the "LEGACY" category affected by this option?
That's not what this is about... it is about how you find the root pointer.
On a BIOS system it is found by scanning low memory. On an EFI system it is found by querying EFI for a specific UUID.
