i2c-nvidia2 doesn't exist as far as I know. You must refer to
i2c-nforce2, I presume? If so, this is totally unrelated with the
busses found on graphics adapters. i2c-nforce2 is meant for motherboard
SMBus.

Search for rivatv instead - see my other post.

Rudolf's w83785 driver is meant for the Winbond W83L785R chips, which
is a full-featured hardware monitoring chip. My w83l785ts driver, OTOH,
is meant for the Winbond W83L785TS-S, which is a very simple
single-temperature sensor. I think I remember both devices are
compatible, in that you should get proper temperature readings if
forcing the w83l785ts driver on a W83L785R chip. Both drivers could be
merged to make things easier, but nobody had an interest in working on
it so far, it seems.

rivafb, nvidiafb.
