On one of the servers I manage, which is a Debian Lenny (Testing) running on Tyan S3992-E, I get the following kernel message when trying to load the lm85 driver: [5792969.531820] i2c /dev entries driver [5793015.944697] i2c-adapter i2c-0: lm85: Detected SMSC chip [5793015.944757] i2c-adapter i2c-0: lm85: Unrecognized version/stepping 0x68 Defaulting to Generic LM85. [5793015.944853] hwmon-vid: Unknown VRM version of your x86 CPU The kernel used is "linux-image-2.6.26-1-amd64 2.6.26-13". The lm-sensors package is version "1:3.0.2-1+b2". Hope it helps.
