What a painful process... first time I built the kernel from the rpm source I must have stuffed something up and the resultant installed rpm didn't have the module turned on.. aaarrrrggghhhhh... Trying to rebuild the srpm again after tweaking the .config file and copying it around to the various locations again just didn't work.. Eventually gave up and had to rip it all out and start afresh.. Well spotted on that one.. What a pain that the call to the i2c mux create didn't result in a error :/ Now I just need to shutoff kernel updates.. Really need to push this up into the centos config.. I've noted that it has been turned back on in other releases.. Will submit a bug.
