I have my kernel built with dev-i2c and i2c_i801 but do not have a /dev entry.

kernel ver:
Linux vega 3.18.0-rc1+ #71 SMP Wed Oct 22 00:49:21 EDT 2014 x86_64 GNU/Linux

lspci -nn shows this:
00:1f.3 SMBus [0c05]: Intel Corporation 5 Series/3400 Series Chipset SMBus Controller [8086:3b30] (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?
