I'm fairly certain that the Turion X2 and the Athlon X2 6000+ are both K8 based which means Solaris is not able to power manage them. The Athlon X2 6-series that I referred to are (from what I've read) a rebranding of the Phenom X2. That might have changed. The bottom line is that Solaris does not support CPU power management of K8 based processors, but does support CPU power management of K10 based processors.
