After reviewing the output from dmidecode I determined that your model T60 is slightly different than mine. It appears that you have the widescreen version. Is that correct?

Also you seem to be running a fairly old version of the BIOS (1.08). The latest is 1.18:

I would recommend that you upgrade your BIOS. If that does not help we can continue with the investigation. I will also try to locate a widescreen T60 that would hopefully help me with the repro. 

The model I have has been running all kinds of stress since you first reported this issue, and so far is rock solid.
