What do you mean? hwmon-enabled thinkpad-acpi? I'm seeing 
/sys/devices/platform/thinkpad_hwmon directory, is that it?

And BTW, thanks - I just discovered the sensors.conf file and now I have 
a similar sensors output except that I have no way to figure out what 
temperatures number 1, 2, 3, 4, 9, 10 and 11 show on my Z61m - I've 
searched the Internet unsuccessfully - is there any way to find out this 
maybe from IBM, err... Lenovo?
I'm not keen on opening my ThinkPad, finding them on my own and then 
cooling them down while having the ThinkPad on... [?? is that how Milos 
Popovic did it with his A31 (as reported in ThinkWiki article titled 
Thermal Sensors)?]

Well, it is new, but then again I didn't bother to log the temperatures 
down so I really don't have any real data... For example, after this 
discussion, I've been monitoring it (manually) a bit more often and I've 
seen it go even up to 32°C on cells during heavy usage.
