Unable to dynamically set CPU frequency

[Tim R <therealclicksy%yahoo.com@localhost>]

I installed NetBSD on a HPNX9420 laptop with a dual core 
CentrinoT2600/2.16GHzCPU 
With the Generic kernel both cores revs up to maximum frequency and stays 
there. 
This result in high temperatures within a few minutes and the fan is constantly 
on 
max speed and noise. I installed estd-0.7 from pkgsrc. When I ran estd for the 
first 
time it said it can not guess CPU-scaling technology. Ok, so I built a new 
kernel 
where I enabled odcm0 in the conf file. est0 was already enabled. I rebooted 
and ran 
estd again. Same message, can not guess CPU-scaling. Now I built a new kernel 
where 
I added the following options to the conf file: ENHANCED_SPEEDSTEP, 
EST_FREQ_USERWRITE and INTEL_ONDEMAND_CLOCKMOD. Rebooted and ran estd again, 
same 
result, can not guess CPU-scaling.

This laptop runs pretty cool on other os' including Ubuntu and Windows so 
clearly 
THOSE os' are able to modulate the frequency. What are my options here? Are 
there 
other configuration options I should compile in? Any other programs out there I 
can try in order to control cpu frequency? Any help appriciated.

Here is some of the dmesg output
