...ntk traces, I saw that probing i2c bus 3 for sensors always failed with -EIO (no ack from slave). After reading the code, remembering how i2c works and reading sample code on wikipedia, I couldn't identify any algorythmic problem. So I gave a try at changing delays. I doubled T_RISEFALL and T_HOLD, and the adt7473 chip could be detected & used again. I haven't tested other combination, nor tried to link those delays with any datasheet. My card is a GTX 280.
