You should first try to reproduce this on a mainline kernel.
Is the thermal driver loaded?

If it's a Debian specific patch..., I don't know how to bisect them but you
should try to find out which one is the offender and post on a debian site.

If this is a mainline problem you might want to revert all _OSI(Windows) from
OS. Or better only return true for _OSI("Windows 2006"). ThinkPads store the
running OS in separate variables and do not use the Intel OSI template.
Therefore you likely run in untested VISTA + XP + NT + XY DSDT paths.

This currently is hardly possible, I plan to blacklist Lenovos to only return
true for "Windows 2006", they all support Vista.
If you have a mainline kernel problem, watch the list, maybe this patch will
help you.
