 Okay, I've kept quiet only because I expected someone else to chime in by 
now, but since that's not happening...what the heck.
 From my understanding/experience with CPU scaling, /proc/cpuinfo reports 
the reduced CPU speed until there's a CPU load that kicks the scaling up.  
Simulate a load (seti/folding at home, whatever) and /proc/cpuinfo ought to 
change.
 But, I could be wrong; I haven't played with scaling much.
