Actually everything I've read says that the G5/970 CPU has dropped the
feature that allowed it to run in either big or little endian mode.  This
was one of the reasons MS had so much trouble with getting VirtualPC working
on a G5.  The version that'll actually run on it still has not come out.

So I believe everything up to the G5 supported the feature, but for some
reason the G5 does not.
