I have my kernel built with dev-i2c and i2c_i801 but do not have a /dev entry. lspci shows this: 00:1f.3 SMBus: Intel Corporation 5 Series/3400 Series Chipset SMBus Controller (rev 06) dmesg shows this: [ 1.566003] i801_smbus 0000:00:1f.3: enabling device (0000 -> 0003) ls /sys/bus/i2c/devices/ shows nothing... on running this on a MacBookPro6,2 What am I missing? Shouldn't I see a i2c device? I think SMBus is a subset of i2c and I should be able to use that subset, right?
Having looked into this a bit, but failing to come up with something helpful, I decided to ask some additional info. On Tue, 2014-10-21 at 21:54 -0400, John de la Garza wrote:

What are the PCI vendor and device codes? See "lspci -nn".
