Problem with cpufreq on Geode GX1

Hi all,

I'm trying to use cpufreq on my Geode GX1 board with linux-2.6.12.5, but, while everything seems OK, i.e., I can change from performance to powersave governor and back and /proc/cpuinfo reports me frequency changes, I can get no effective frequency/CPU power change because I check it with the Whetstone benchmark and it allways give me the same value (~100 MWIPS). Any ideas from were could be the problem?

Some additional info follows:

$ cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor

performance

$ cat /proc/cpuinfo

$ echo powersave > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
