Hi, I use a laptop with a Turion 64 mk-38, and the scaling works fine in Ubuntu Studio 7.04. I install the powernowd package for the Debian etch repository, and at moment to start the module this error occurs: PowerNowd encountered and error and could not start. Please make sure that: - You are running a v2.6.7 kernel or later - That you have sysfs mounted /sys - That you have the core cpufreq and cpufreq-userspace modules loaded into your kernel - That you have the cpufreq driver for your cpu loaded, (for example: powernow-k7), and that it works. Check 'dmesg' for errors. If all of the above are true, and you still have problems, please email the author: clemej@alum.rpi.edu Answering to the questions, I use the kernel 2.6.21-1-multimedia-amd64, libsysfs2 is installed, and to the other question I really don't know. If some one have any idea, please tell me, Best Regards.

What do you want to use your 64Studio installation for? If your answer is audio, I would stick with the realtime kernel, and forget about scaling. Because the audio happens in real time, and your CPU clock is used in all the audio app, and in the Jack server you might detect some artefacts the moment the scaling occurs. These will be "xrun less" pops or clicks, and is not a good thing in audio as you can imagine. Think of the realtime kernel as a top fuel dragster. It wants to run at full throttle, and anything less will compromise the run. On the other hand, use the search function in the top right of this page, and type "powernow". There are some success stories to be told, for instance: http://www.64studio.com/node/436 Hope it helps,
