Installing CHDKPTP was slightly painful. Not quite point and click
however I have it running on my laptop now.
It works, most of the buttons do what they should and it takes pictures.
Result of the suggested test "rs -jpg"

Only gotcha discovered so far, if I select some of the shooting modes by clicking the drop down list below the [REC] and [PLAY] buttons I can crash the camera.
