I would like to insist on this. The fact that vrm is writable is a legacy of the past. There is no more reason to set the vrm value now that Rudolf Marek added auto-detection stuff (which BTW should be ported back to lm_sensors CVS). Even exporting the VRM version to user-space makes little sense now. This now only serves for debugging, but this would be more efficient to simply print the VRM value in the logs at the moment we detect it. -- Jean Delvare
