Hello,

I have an IBM R50 E with a Intel Celeron 1.4 Ghz processor installed with 
10.3. Recently I discovered that simply loading the module p4_clockmod scales 
down the CPU-frequency to about 170MHZ and as needed scales the freq up.  
This helps saving battery power.

What I would like to do is to set a lower limit beacuse sometimes the 
interaction feels quite slow because of the very low initial frequency. So 
what I would like to to is to say: 

Use eg 500MHZ as a lower limt for downscaling the CPU and scale up as needed. 

On my P4 Desktop I once had such an option where I could say eg:

echo "500" > /sys/devices/system/cpu/cpu0/cpufreq/scaling_min_freq

to get this done but in 10.3 there is no such proc entry. Any other way to get 
this done?

Thanks
Rainer Krienke
