I was thinking about using the 'force' parameter to givie the address 
explicitly to the module, the device may be on non standard port.
sensors-detect is usually more capable of detecting devices than kernel 
modules

Haven't read the source of this module, but you'll probably have to compile 
kernel (or at least the module) with different .config (one that enables 
debugging messages)

I'm just a random lm-sensors user, so it's more of the blind leading the blind 
case and educated guess than real inside knowledge about lm-sensors...
Though there are other readers from the list that will benefit from this 
information
