Well my hardware is an HP N40L so thats really my problem. I have had to compile a jc24.ko module for the kernel. Install it and make sure that was loaded. Ran sensors-detect and now its detected and ends up as an entry in my lm_sensors.conf file. So yipee but still not seeing anything other than the processor temp when I run sensors.
So I am pretty sure I have it configured ok but I have seen loads of posts on the internet where people have been having the same problem getting lm_sensors to display sensors on this hardware regardless of distro. So I am giving up
