I have the following line in my kernel configuration:

> CONFIG_I2C_I801=m

Following i2c/smbus-related modules are loaded:

> lsmod | grep i2c
                                                                :(
> i2c_smbus              16384  0
> i2c_i801               24576  0
> i2c_algo_bit           16384  1 i915

lshw has the following output specifying i801_smbus as driver:
