Ah ha!  Note that while the CPU records in the {MPS,ACPI/MADT} table are in 
numerical order (as preserved in raw_phys_apicid), the boot CPU is # 02.  The 
flat code in smp_boot_cpus assumes that the boot CPU will be the first record 
in the list.  Oops.

Try the attached patch and see if it helps.
