SO, why can't i modprobe ondemand?

speedstep_lib and speedstep_ich both seem pleased to load..

cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_governors

comes back with;
conservative ondemand userspace powersave performance

which i'm guessing is what the kernel has loaded, not necessarily what
the BIOS is supporting..

The cpu is indeed model 11, according to /proc/cpuinfo,

SpeedStep is indeed on in the BIOS.. and the BIOS is the latest version.

I've even tried passing relaxed_check=1 to the speedstep_lib module.. no
good. And nor does speedstep_smi want to load no matter what, which i'm
not sure is even relevant.

kernel is 2.6.15-1-686 debian stock.

what am i missing? Why can't i echo ondemand >
/sys/devices/system/cpu/cpu0/cpufreq/scaling_governor

without getting:
bash: echo: write error: Invalid argument

?
thanks in advance
