Ok. Is there any programmatic way to determine whether a given Dell 
complies with your WMI spec or not? I'd prefer not to use DMI tables 
unless it's the only way to identify the machines - the risk is that 
there'll be something else that also uses its own codes and will just 
behave oddly until someone figures out why it's broken.
