These EEPROMs have a state machine bug which makes them vulnerable, so other tools and OSes could corrupt it as well. However, as far as I remember, the corruption cases that were reported to us were fatal, in that the laptop would not boot anymore.

Make sure your system won't load related drivers for you at boot time. If you ran sensors-detect and let it create it's configuration file (typically /etc/sysconfig/lm_sensors), the modules listed in that file will be loaded at boot time, and you don't want this to happen. To be safe, delete or blank that file. -- Jean Delvare
