Comment 9 for bug 580189

I have the same processor and chipset in my Thinkpad A20m. The userspace governor + Powernowd worked well in Hardy, but was locked at 700MHz upon a clean install to Lucid. (Note: the "too long transition latency of HW" always meant the ondemand governor wasn't available for this laptop.) I noticed the /sys/devices/system/cpu/cpu0/cpufreq directory was absent with my Lucid installation, yet present with if I booted the Live CD. After some trial and error I was able to get this directory to appear by removing Grub 2 and falling back to Grub legacy, and now my userspace + Powernowd works (it steps between 550Mhz and 700Mhz, depending on load.)
