The applet can only report what SpeedStep setting the CPU reports.  That 
doesn't accurately reflect the effective speed of the CPU which is a 
multiple of bus speed.  But we can determine that there was a change by 
indirect means (aside from directly reading cpufv):

Run three trials at each of the settings of this crude benchmark:

time sh -c "echo '2^2^20' | bc > /dev/null"

Or else use find & use some bona fide CPU benchmark.
