cpufreq and absolute drivers

Hi,

I've been using ichist.ko by today before I switched to current. Cpufreq 
says it unites absolute and relative drivers. As far as I understand it 
absulute drivers are hardware based and relative ones are not? As I 
would like to use ich support again to get speedstep running I tried to 
find something about that in the man page of cpufreq. It is talking 
about ichss(4), however I cannot find this module.

Thanks for the hints, Jochen
