But it happens that Benjamin Herrenschmidt has a working i2c bus driver for Radeon boards in Linux 2.6, as part of its new radeonfb driver. The i2c part is much similar to what I had tried, but there is much more initialization stuff in the video part. This is probably what was missing to me. There is no point in writing a separate i2c driver now, so I'm canceling my driver completely. Thanks for the help anyway. -- Jean Delvare http://www.ensicaen.ismra.fr/~delvare/
