Well, the MorphOS 3.12 release notes state the following:

"Added basic PMac12,1/PPC970FX frequency switching support [...]
Basic sensor support for PMac11,2/PMac12,1 models [...]
Added dynamic CPU frequency switching (full/half speed as supported by 970FX) for PowerMac12,1/iMacG5 based on CPU load statistics"

None of these features would make sense being mentioned if the public MorphOS 3.12 release didn't run on those machines, I guess ;-)
