Hi Steve, > Oops! Forgot to mention that I'm using lm_sensors-2.8.7 for the userspace > programs. (Standard with RHEL4). This is the cause of your problem then.

Note that you may want to backport the driver from 2.6.12 rather than 2.6.10 - it has some more bugfixes and cleanups, and the backport should be similarly easy. -- Jean Delvare
