given an ioapic, the mp table just doesn't have enough information
to uniquely determine vector mappings. unfortunately this problem was
never solved. (vendor's answer: use acpi instead.) this is a leading
cause of "broken" mp tables. another leading cause is forgetting to
delete entries for hardware that bios has configured off.
