 * 16 8259A IRQ's, 208 potential APIC interrupt sources.

 * Right now the APIC is mostly only used for SMP.

 * 256 vectors is an architectural limit. (we can have

 * more than 256 devices theoretically, but they will

 * have to use shared interrupts)

 * Since vectors 0x00-0x1f are used/reserved for the CPU,

 * the usable vector space is 0x20-0xff (224 vectors)
