I'm still not happy with just DMIing this. If Windows is behaving 
differently in terms of choosing which values to use, we should be 
duplicating that behaviour - there may well be other affected systems. 
Working around it for these specific machines just means it'll take 
longer to fix properly. Thomas, can Lenovo provide any information about 
why this hardware works in Windows?
