Hi Isaku, I tried your updated patch, and xenpm works in my IPF box. the attached is the xenpm output.

You can double confirm by: - check BIOS to see if DBS is enabled. - or try the native linux (e.g. RHEL5), to see if the cpufreq works. Also, it will be helpful if you can attach the xen serial log. please add "loglvl=info" to elilo xen option, to make sure cpufreq information is printed.
