Unfortunately, the sensors-detect only reported "No" for each Super I/O  
chip test, while the superiotool gave an unhelpful "No Super I/O chip    
detected" message.                                                       

I haven't heard a response yet from WinSystems, but I'll give them a     
couple days before sending another email to their engineering            
department. For now, I'll submit a version 4 of this patch to get the    
minor updates I made out for review; for what its worth, I believe the   
dmi_match method will be sufficient until I get an update from           
WinSystems helping me get a proper check to identify the Super I/O chip.
