Hi Danny, Looks like the BIOS update have solved your cpu power management problem. I see from the kstat info that both the cpu's are at their lowest freq of 2 GHz.
Regarding the messages about T states, it gets logged if the processor does not support ACPI T-States. It does not effect power management in any ways. I am about to putback a fix where T-State messages will only be enabled through Dtrace therby this confusion will not arise.
