Not quite correct.
The PS3 runs the Cell processor, who is a descendant of the PowerPC.
Currently, (as far as I know) the PS3 is the only commercial system to be
using it. IBM may be using it on their systems that get sold under one of
their many trade names.

Anyway the way he did the supposed liberation has been called into doubt by
people claiming to be familiar with this event.

Robert where did you find this bit of news? I came across it on the nearly
recent entries into the Hack A Day site, the decidedly
rude and probably not correct in most cases are doing that.
