Dude, thanks for your post-mortem of P4 HT, but you're totally confused on the technical details. There's no such thing as a "hyperthreaded application", you don't need to rewrite software to take advantage of SMT, and marketing never took part in its inception, implementation and deployment. Not to mention SMT not even mutex with multicore, you can have both.
And you're confused with this new concept as well, which I assume to be intel's mitosis and the amd equivalent which is rumored to exist on AM2 and/or K8L (but certainly does not). I am so confused by your post I can't be sure what you are referring to. There's no software involved in intel's mitosis other than the fact that static optimizations would greatly benefit such a hypothetical machine, and the aforementioned machine is just a single processor to begin with, not multiple cores.
Please read Vidtor's link before further speculation, thanks.
