And the MSR 0x611 MSR_PKG_ENERGY_STATUS was only introduced in Sandybridge according to "Table 35-12. MSRs Supported by Intel® Processors based on Intel® microarchitecture code name Sandy Bridge" of the Intel® 64 and IA-32 Architectures Software Developer’s Manual.

I therefore believe powertop may be reading power MSRs that may be bogus for Arrandale.
