If you download sysprep 1.1 from MS's website it will allow you to build an image for multiple HD controllers. They also include numerous default PIDs to include in your sysprep.inf.

Also, IIRC, in cmdlines.txt you should put in sysprep.exe -clean to remove the extra PIDs after the initial install. I cant find the link on this feature ... maybe google.
