That doesn't make sense: no sensors/hwmon chip needs the eeprom module.

So, sensors-detect doesn't find vt1211?  Can we see the full output?

What modules are loaded and/or builtin when you run sensors?

If you were running a 2.6.x kernel when you built libsensors, then it almost
certainly did the right thing.  You can run 'ldd `which sensors`' to be sure.

Reply-to-all with the requested info.  Thanks.
