Funny. It's not doing this on my Prescott. Now, is it clever enough to
install nothing but the right kernel on this system, or dumb enough not to
realize that an SMP kernel makes sense on a UP system with HT enabled?

Well, there is no such thing as a non-SMP EM64T system since they all
have hyperthreading. If they just had kept the "smp" in the version...
