My Error. It may be related. Try without loading ln-sensor/temp modules.
I don't think your mother board supports the i2c stuff you are loading.
You have the Intel 440BX AGP chipset and there is not i2c interface on it.

As far as the temp stuff, it does support i2c over the smbus.
$ sensors
max1617-i2c-0-1a
Adapter: SMBus PIIX4 adapter at 0850
Board: +48C (low = -55C, high = +127C)
CPU: +49C (low = -55C, high = +110C)
Whether its recommended or not, not sure, I'll try later today w/out it.
