There is a need to tunnel those somehow since ACPI/DMI tables resides in
a guest memory. Guest BIOS can build them, but some folks want to pass
additional ACPI tables from command line. So if CPUID is not suitable for
this there have to be another channel. CPUID can provide info if this channel
is available.
