Stefan,
Please check out the code from the CVS code.
After LinuxBIOS keeps the bsp to still use apicid 0. Kernel (2.6.10) x86-64
can work well.
Andi suggest that. But I wonder why the normal BIOS (kernel with acpi
enabled) can lift that to 0x10. --- normal BIOS (kernel with acpi disabled)
will fail too.
I also CC the kernel guys relating to this.

Enable apic ext id committed.
Changes
Auto.c
nodeid = lapicid() & 0xf;
#if ENABLE_APIC_EXT_ID == 1
enable_apic_ext_id(nodeid);
lapic_write(LAPIC_ID, ( lapic_read(LAPIC_ID) |
(APIC_ID_OFFSET<<24) ) ); // CPU apicid is from 0x10
#endif
if (cpu_init_detected(nodeid)) {
asm volatile ("jmp __cpu_reset");
}
distinguish_cpu_resets(nodeid);
also reset_test.c
change cpu_init_detected and distinguish_cpu_resets to take node id.
