I didn't look at the module sources, due to the fact that I won't know
what I will read :-) but as far as I can see in the documentation, and
looking at the behaviours, it seems that wire and wire_therm modules
interact with the Sysfs interface (/sys/class/gpio). So we should need
modules that interact with the character device. Isn't it (more or
less)?

Thank you very much for the clarifications and for your efforts.
