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.)
