I'm far from an expert on the subject, but my understanding is that the primary enhancement of x2apic over apic/xapic is 32-bit vs 8-bit addressability of the proc for interrupts. Apic/xapic should be capable of having 255 interrupt processors registered, which should be more than any of our laptops would need.
