Please make sure you don't have *two* libsensors on your system. If you
have two sensors programs, it could mean that you also have two libs
installed and we know it has caused problems to many other users. So,
first remove any old lib and sensors program.

The second thing to try is to use i2c and lm_sensors 2.6.5 instead of
2.7.0. This last version has had many changes and knowing wether the
previous one works for you is helpful to us.

As far as i2c-velleman is concerned, I fear there's nothing we can do.
Just don't try to load it unless you know there is such bus on your
