yum install i2c-tools
modprobe i2c-dev
ls /dev -> should now show a list of all /dev/i2c-0...255 devices

add to last in file /etc/rc.d/rc.local 
/sbin/modprobe i2c-dev

$ su -
$ gedit /etc/sysconfig/modules/i2c-dev.modules

Add lines:

#!/bin/bash
lsmod | grep -q i2c-dev || /sbin/modprobe i2c-dev >/dev/null 2>&1

Save and exit. Make it execuable
$ chmod +x /etc/sysconfig/modules/i2c-dev.modules
