You might need a newer kernel. At http://www.lm-sensors.org/wiki/Devices
it says "support for Clarkdale and later cores was added in kernel 2.6.35,"
which your i5 M450 seems to be, according to
http://en.wikipedia.org/wiki/Intel_Core_i5.

Try installing a more recent kernel like 2.6.39 from Squeeze backports [1].

1: http://packages.debian.org/squeeze-backports/linux-image-2.6-686

Sorry, I just realized that you are on a 64-bit machine. Try this:
http://packages.debian.org/squeeze-backports/linux-image-2.6-amd64
