Powerd not working with C2D CPUs ?

[Frank Staals]

I recently aquired a new laptop; A Dell Latitude D630 which has a C2D 
T7300 as cpu. Just about the first thing I did was enable powerd, 
allthough that doesn't realy seems to work; the CPU-speed doesn't 
decrease when the system is idle ( or at least dev.cpu.freq is always 
2001 where at my previous laptop it went to an lower level when the 
system was idle ) . The freqlevel is still at 2001 when `top` shows the 
CPU is 97% idle.  Anyone else with a C2D cpu running powerd which has 
this problem or am I just doing something wrong :
