How so? The XAPIC version check should work there.
ACPI: LAPIC (acpi_id[0x11] lapic_id[0x21] enabled)
Processor #33 15:4 APIC version 16
ACPI: LAPIC (acpi_id[0x12] lapic_id[0x26] enabled)
Processor #38 15:4 APIC version 16
This is a boot message excerpt from one of the "Potomac" systems we
have. x86_64 kernel without xapic check, therefore the CPUs are
activated, but they wouldn't be on recent i386.
I fixed that in the 64bit version already, but not in 32bit yet.
Yes, the value of the APIC IDs must be used as indicator.
Great.
