No actually its our bug. Some BIOSes contain template SMP tables which have
intentionally incomplete data and no checksum. This is used by the BIOS to
generate a real table if SMP is present.
We should not be reporting a wrongly checksummed SMP table we should be
skipping it silently. This used to be right in 2.0 but someone has obviously
elevated debugging code too far since.
