Thank you Gordon, I downloaded the original .rpm and extracted the files that I had changed during my testing and replaced them on the system. Its working now. Strange, as all I had done was copy the relevant .ko's elsewhere for safekeeping while I was testing and the fault arose when I coped them back. Weird.....
