  Or: how to start a multicore (hyperthreading)
processor as if it were
 a singlecore (non-hyperthreading) processor.
 
 Would it be necessary to configure APIC/IPI in serialice' mainboard
 specific code?
You probably need something like:

        /* Send INIT IPI to all excluding ourself. */
        movl    $0x000C4500, %eax
        movl    $0xFEE00300, %esi
        movl    %eax, (%esi)
