Ahh. There are apparently two different things: an IO-APIC, which is on some
CPUs, and an APIC, which is on some motherboards. All SMP machines have an
APIC, but an IO-APIC is optional per CPU, and not required for SMP.
Check /proc/cpuinfo to see if you have an IO-APIC, and I don't know where to
see if you have an APIC. I, for example, have neither on my UP athlon 750.
