 In mpacpi_config_cpu(), as x2apic_mode=0, the ACPI_MADT_TYPE_LOCAL_APIC
 case is followed, and
 
 lapic->Id=16
 cpunum=32  !!
 
 => role=2=application processor rather than boot processor.
 
 cpunum = i82489_cpu_number()
 
 If only there were 32 cpus in this laptop - non-consecutive numbering?
 Should be using x2apic?
