So this is unlikely that what sensors-detect finds is an adm1021 or compatible chip (I guess it pretends to find a lm84 or a max1617, two highly difficult to detect chips). The solution would simply be not to load the adm1021 driver at all. If you want me to take a look at what the chip could be, you can provide the output of i2cdump for it. That said, I don't expect it to be a hardware monitoring chip, so I probably won't be able to identify it. > It may be of interest to note that the new radeonfb driver includes an > i2c interface which is detected by sensors-detect and the i2c > interface itself is detected by the radeonfb driver.

It does indeed give access to up to 4 i2c busses on the board. The only thing you can see there are DDC eeproms from connected monitors. They help radeonfb (and the X radeon driver) to detect the correct resolution and frequencies for your monitors. We have a driver for this for 2.4 kernels (ddcmon) but it hasn't been ported to 2.6 yet. You can also use the eeprom driver (which is ported to 2.6) and the proc/eeprom/decode-edid.pl script (together with the read-edid tool). -- Jean Delvare http://www.ensicaen.ismra.fr/~delvare/
