[Solved] Missing ‘combined’ file in ‘/sys/module/i2c_bcm2708/parameters’ directory

tommyr Asks: Missing ‘combined’ file in ‘/sys/module/i2c_bcm2708/parameters’ directory
Following Adafruit’s instructions for their capacitive touch sensor (MPR121 Capacitive Touch Sensor on Raspberry Pi & BeagleBone Black) I’m getting the error message when trying to run their example python script:

Code:
pi@raspberrypi ~/Adafruit_Python_MPR121/examples $ python playtest.py 
Adafruit MPR121 Capacitive Touch Audio Player Test
chmod: cannot access `/sys/module/i2c_bcm2708/parameters/combined': No such file or directory
Traceback (most recent call last):
File "playtest.py", line 37, in <module>
if not cap.begin():
File "/usr/local/lib/python2.7/dist-packages/Adafruit_MPR121-1.1.0-py2.7.egg/Adafruit_MPR121/MPR121.py", line 90, in begin
I2C.require_repeated_start()
File "/usr/local/lib/python2.7/dist-packages/Adafruit_GPIO-0.9.3-py2.7.egg/Adafruit_GPIO/I2C.py", line 81, in require_repeated_start
subprocess.check_call('chmod 666 /sys/module/i2c_bcm2708/parameters/combined', shell=True)
File "/usr/lib/python2.7/subprocess.py", line 511, in check_call
raise CalledProcessError(retcode, cmd)
subprocess.CalledProcessError: Command 'chmod 666 /sys/module/i2c_bcm2708/parameters/combined' returned non-zero exit status 1

I’ve checked the contents of the parameters folder and it’s empty apart from a file named ‘baudrate’.

The Pi is a Model B – Series 1. Raspbian is up to date.

I’ve searched high and low but cannot find a fix.
