lm_sensors 3.3.2 just came out last week with this in the ChangeLog [1]: "Change sysfs detection to survive upcoming kernel changes"
I'm not sure if that means kernel 3.3 or newer, but just a heads up (mainly to tmb) that we might need this. [1] - http://www.lm-sensors.org/browser/lm-sensors/tags/V3-3-2/CHANGES
