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.
