It does work for me, i have these directories:
/sys/devices/system/cpu/cpu0/cpufreq/
/sys/devices/system/cpu/cpu1/cpufreq/
$ grep "model name" /proc/cpuinfo
model name : AMD Athlon(tm) 64 X2 Dual-Core Processor TK-55
model name : AMD Athlon(tm) 64 X2 Dual-Core Processor TK-55

$ uname -a
Linux terminaldelmal 2.6.26-1-amd64 #1 SMP Sat Jan 10 17:57:00 UTC 2009 x86_64 GNU/Linux
$ grep power /proc/cpuinfo
power management: ts fid vid ttp tm stc
power management: ts fid vid ttp tm stc
Also, on my /etc/modules, i have these:
cpufreq_conservative
cpufreq_ondemand
cpufreq_powersave
cpufreq_stats
cpufreq_userspace
And these too:
k8temp
powernow-k8
Also, just in case, i have this in my /etc/rc.local
echo conservative > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
Hope it helps.
Regards
