I think every processor since Pentium 1 has a Local APIC built in --
at least all the processors from Intel.

If you build in support for it, you can disable it with "nolapic".

Note that LAPIC is required to support IOAPIC -- which is a motherboard
device in the chipset. This on can be disabled with "noapic".
