Its irrelevant in the big picture. The "new power management scheme" I'm talking about addresses the whole platform, while Temash will do more of the same they did in the previous generation - cut power in the CPU side which is already very very small.
We don't know yet whether Temash will offer something similar to s0ix. At this point, it's simply a likely assumption that they won't but it isn't a certainty. They've got a demo coming up at the MWC though so hopefully we'll learn a few more details very soon.
