Tracing of power:power_start events doesn't work

[Ronny Tschüter]

Hello,

i use kernel version 2.6.33.2 (x86-64, Core 2 Duo) and the perf events 
to track frequency and c states of my cpu. But if i want to trace 
power:power_start events, it does not work. After typing

echo "power:power_start" | sudo tee set_event

on the console, the trace doesn't contain such events. 
power:power_frequency and power:power_end events are reported correctly 
by the system. I read in the mailing list that Robert Schoene had a 
similiar problem, but with power:power_end events. Is there a known bug 
regarding to trace_power_start methods in process.c?

Bye Ronny
