Introduction to Multithreading, Superthreading and Hyperthreading

Conceptually, what's the difference between Hyperthreading, as popularized by Intel in the Xeon processors, and Simultaneous Multithreading (SMT) of the POWER5 chip? Apparently, they're one and the same.

The article from Ars Technica, Introduction to Multithreading, Superthreading and Hyperthreading gives the low down on everything related to the subject.

I am still curious, though, on what the actual implementation differences are.
