IDA, Intel Dynamic Acceleration.. WTF is that?

Taken from this Ars Technica news article.

This new technology allows the FSB to be underclocked when desired in order to save power. Previously, Centrino processors operated in Low Frequency Mode when set for reduced-power operation, but the FSB was kept at full speed. By cutting the FSB speed in half using Dynamic FSB switching, Santa Rosa should be able to save more power than before. Intel refers to this combination of chip-and-FSB underclocking as Super Low Frequency Mode, or Super LFM.

The thing you're talking about is real, but I believe IDA is something different. It's hard to find good technical details (or I'm not very good at finding them, at least), but it looks like IDA has to do giving dual-core chips more flexibility when dealing with serial or asymmetric loads -- supposedly by ramping up the clockspeed on the chip that's actually working, while the other one sleeps in a low-power state, thus making more effective use of the same number of watts.
