Do you have i801_smbus driver enabled and loaded?

I have the following line in my kernel configuration:

quoted

CONFIG_I2C_I801=m

Following i2c/smbus-related modules are loaded:

lsmod | grep i2c

                                                                :(

i2c_i801               24576  0
i2c_algo_bit           16384  1 i915

lshw has the following output specifying i801_smbus as driver:

Hmm, what about rmi_core and rmi_smbus? It might be quicker if you send
your dmesg, .config and lsmod...

Thanks.
