this semms not to be a valid argument here

having a P4 1.8GHz do I need stock_freq=1800000 ? (tried, it works)

let' start:

# modprobe p4_clockmod stock_freq=1800000

# echo *ondemand* > /sys/.../scaling_governor 
--> never returns

some infos from an ssh login:

after that echoing something else (tried with powersave) never
returns too...

what other info can I supply?

I tried playing with cpu-usage (compiling kernel) but
/sys/devices/system/cpu/cpu0/cpufreq/ondemand/current_freq always shows
1800000
