This looks reasonably similar to the other SMBus controllers from
nVidia. Are you willing to take your chance?

If you are, here's what you need to do (as root):
# modprobe i2c-nforce2
# echo "10de 0752" > /sys/bus/pci/drivers/nForce2_smbus/new_id
# modprobe i2c-dev
# i2cdetect -l
# i2cdetect <n>
# i2cdetect <n+1>
where <n> and <n+1> are the i2c bus numbers of the two nForce SMBus
channels.

If this gives resonable results I will add the new device ID to the
sensors-detect script and the i2c-nforce2 driver.
