> MorphOS already does power down the unused cores

Very nice :-) Has this been the case since MorphOS 3.10 or been added later? I don't remember I already read this, at least looking through the release notes since 3.10 I cannot find anything with respect to this.
Btw, has this feature also been added for PowerMac11 (PPC970MP) meanwhile? (I know that generation isn't officially supported, and that MorphOS supports this on PowerMac7 (PPC970/PPC970FX) since MorphOS 3.10).
