Hi, With kernel 2.6.0-test1 (likely with lm-sensors 2.8.0 too), it is possible to load both via686a and i2c-viapro, but only one of them will work, depending on which was loaded first. The reason for this is, that both drivers feel responsible for the VIA_82C686_4 and once the probe was successful, it is registered only to the driver which was loaded first. (So, you can load another driver for the device but the probe function will never get called). Sorry for not providing a patch, I have on clue how to fix this properly. Bye, Christoph
