Hello,
I just wrote a driver for the SMBus (more precise: the SMBuses) in the nVidia
nForce2 southbridge (based on the AMD-8111 driver). It runs both with version
2.6.5 and with CVS. Although it is not very well tested, it runs perfectly on
my computer and I think it might be useful for others as well. Please include
it in lm_sensors.
Cheers,
Hans-Frieder

Kernel driver `i2c-nforce2.o'
Status: Beta, although no problems found during one month usage with hwsensor
Supported adapters:
* nVidia nForce2 SMBus PCI interface (10de:0064, included in nForce2 MCP)
Datasheet: not publically available, but seems to be similar to the
AMD-8111 SMBus 2.0 adapter.
Author: Hans-Frieder Vogt <hfvogt at arcor.de>
Module Parameters
-----------------
None.
Description
-----------
i2c-nforce2 is a driver for the SMBuses included in the nVidia nForce2 MCP.
If your 'lspci -v' listing shows something like the following,
00:01.1 SMBus: nVidia Corporation: Unknown device 0064 (rev a2)
Subsystem: Asustek Computer, Inc.: Unknown device 0c11
Flags: 66Mhz, fast devsel, IRQ 5
I/O ports at c000 [size=32]
Capabilities: <available only to root>
then this driver should support the SMBuses of your motherboard.
Notes
-----
The SMBus adapter in the nForce2 chipset seems to be very similar to the
SMBus 2.0 adapter in the AMD-8111 southbridge. However, I could only get the
driver to work with direct I/O access, which is different to the EC interface
of the AMD-8111.
Tested on Asus A7N8X. The ACPI DSDT table of the Asus A7N8X lists two SMBuses,
both of which are supported by this driver.
