There have been recent cases where OEM's want to use the OEM_ID in the
ACPI tables to brand their own product. The UV BIOS used that field to
tell the Linux kernel which UV arch the running system is. The Arch
Type in the UVsystab (also created by UV BIOS) now carries that field in
systems that support it.
