ondemand cpufreq governor

[thomas bonfort <thomas.bonfort@gmail.com>]

Hello,

 I've been trying to get the ondemand cpufreq governor to work on my
ibook g4 1.2.
when I 
"echo ondemand > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor" 

I get a "echo: write error: invalid argument"
the other governors work as specified (userspace. performance, powersave).

I suspect the error comes from the transition_latency defined for 7447
cpus, set to CPUFREQ_ETERNAL.
Does this mean the ondemand governor cannot be made to work on this platform?

cheers,
thomas
