Did you try using powerd and/or Cx states of your processor? 
There are several discussions about these things found at mobile@, stable@ and many other places. For example, this thread at FreeBSD forums: http://forums.freebsd.org/showthread.php?t=172

P.S. As I know from reading list discussions, some IBM Thinkpads really have problems with overheating.
You may also read this thread, especially about your laptop model:  http://unix.derkeiler.com/Mailing-Lists/FreeBSD/stable/2008-01/msg00100.html

And here is how Josh Paetzel managed to get rid of overheating (using Lenovo T61): http://www.mail-archive.com/[email protected]/msg96655.html

Hope these links will help you.
