/proc/cpuinfo

/proc/cpu_infodidn't work for me, too.
However it seems to work now(after I changed the governors to be compiled as modules(or the way around?)).
I've now tried both as modules, and compiled in, /proc/cpuinfo works niether report correctly.

If you want to detemine the current real speed of your machine use the procspeed prog I posted some days
ago(04.12, 09.12).
yes, that is the program i spoke of. However, like i said, when /proc/cpuinfo is reporting wrong, my system works it's way back to full speed even though powersave is in the /sys scaling_governor.
It will report the changed speed (clockdown to 1.2ghz) for about 10 seconds, and then will start to report again at 2.4ghz even though the setting haddn't changed.

I think the BIOS is meddling with the speedstep setting [this is more common for older systems, but obviously some vendors still think it's a good idea] . If it were cpufreq, the value in /proc/cpuinfo would be updated as well.
Do you run an ACPI-enabled kernel?

Yes, I have acpi enabled, and to the best of my knowledge, it is
functioning correclty, at least "externally" /proc/acpi/events works and returns events and stuff. Don't know about non visiable internals though.
