We need to have EVENT_POWER_TRACING_DEPRECATED enabled in the kernel config to get the trace events that powertop is expecting. I've verified that this fixes the issue. powertop needs to be fixed as the tracepoints are going to be removed completely in the near future, but in the interim I'm going to send patches for oneiric and precise to enable the tracepoints.
