After checking the Intel chipset docs, I found that it has an i2c controller and it was enumerated on the pci bus, but no driver was loaded for it. I found the i2c-i801 module and the comments in the source say it supports the Cougar Point (PCH) and matches the PCI ID. I'm not sure why it wasn't auto loaded, but after loading it, it seemed to work. At that point I ran sensors-detect, which failed to recognize any known controllers on the bus, but i2c-detect found several addresses that responded. How can I proceed with identifying what these devices are, so that I can hopefully find or write a driver to communicate with them?
