My laptop running Ubuntu 12.04.3 has this SMBus according to lspci: 

SMBus: Intel Corporation 6 Series/C200 Series Chipset Family SMBus Controller (rev 04)

lshw command shows it as unclaimed. Which driver is needed to activate it?

The correct driver would be i2c-i801, of which Intel states that it's compatible with the Series 6 PCH: https://www.kernel.org/doc/Documentation/i2c/busses/i2c-i801

In recent kernels (2.6.12 and later), the option is in drivers/i2c/busses. From 2.6.0 through 2.6.11, the driver was present, but considered experimental.

To find out if the module is present on your system, use modinfo i2c_i801. If the module is found, try to load it using modprobe i2c_i801.
