anaconda/isys/smp.c.  On i386 it walks the MP tables in the
BIOS. These days BIOS providers are screwing up the MP tables every
now and then because the ACPI CPU information is getting used instead
of the "legacy" MP tables in the BIOS.  It's pretty likely that the
BIOS update just fixed the MP tables.
