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.
