With the first run, where you choose i2c-ali15x3, clearly no i2c bus was found, 
so i2c-ali15x3 is the wrong smbus driver for your motherboard. With the second 
run with the i2c-ali1535 driver, clearly an smbus was found, but without any 
sensors connected.

Did you also say Y to the superio chip probes? Does your motherboard have 
sensor readings in the BIOS and or under windows? What would also help is if 
you could tell use the manufacturer and model of your motherboard.

Hans
