I had found lsmod log before this bug.

To compare with the new lsmod, this is not available :

powernow_k8 16608 1
cpufreq_powersave 3200 0
cpufreq_ondemand 11152 1
cpufreq_conservative 10632 0
cpufreq_userspace 6180 0
cpufreq_stats 8416 0
freq_table 6464 3 powernow_k8,cpufreq_ondemand,cpufreq_stats

So I do :
sudo modprobe powernow_k8 cpufreq_ondemand cpufreq_stats cpufreq_conservative cpufreq_powersave

Then
sudo dpkg-reconfigure gnome-applets

Now I can use ondemand and performance options but by default performance is selected.

dmesg give :

[ 4393.138120] powernow-k8: Found 1 AMD Turion(tm) 64 X2 Mobile Technology TL-50 processors (2 cpu cores) (version 2.20.00)

[ 4443.669517] Clocksource tsc unstable (delta = -219982760 ns)

Now conservative mode is not available :
[ 5086.758354] cpufreq_ondemand: Unknown parameter `cpufreq_conservative'

I don't know what can I do now. HELPPP

So I restart my computer and I do :

sudo modprobe cpufreq_ondemand
sudo modprobe cpufreq_conservative
sudo modprobe cpufreq_userspace
sudo modprobe cpufreq_powersave
sudo modprobe cpufreq_stats
sudo modprobe powernow_k8
sudo modprobe thermal

Then
sudo dpkg-reconfigure gnome-applets

Now I have all controls on gnome-applets. But ONE problem persist : Performance is select by default...
How can I do that ?
