If you go back to the previous kernel, does the problem disappear?  Please
test and report (don't go by past experiences).

If it does disappear, what are the highest temperatures your thinkpad hits?

"sensors" from lm-sensors will tell you the current temperatures as long as
the "thermal" and "thinkpad-acpi" modules are loaded (don't run
sensors-detect).
