Core Duos (Yonah) are a mobile chip only, not a full line of processors like the Core 2 architecture (Merom, Conroe, Woodcrest). I suspect the Core 2 chips do not suffer from the same security implications as HT-enabled processors. I'm not certain, but I think each processor has access to half the cache so the only reason it's shared is that it's on the same die and both cores are using parts of it.
