I don't sure about you says. Are you suggesting to boot the other cores from a Hurd server? My idea is about to implement SMP support from gnumach, searching and starting the cpus during the boot.
I can find the other cpus (the local apic and ioapic) from ACPI tables, but after this I need to send an IPI to enable them, and configure their lapic and ioapic.
