Nak.  Are you sure you are running an SMP kernel on it?  The ht flag means
that the processor is hyperthreading capable.  If your dad's lappy doesn't
show 2 cpus, it may be because HT is disabled in the BIOS.  If the BIOS
doesn't have an option for enabling HT, then check for a BIOS update!
Some manufacturers actually shipped machines with HT capable processors
in the early days that couldn't do HT.  Doesn't mean the processor wasn't
capable of it.
