I've actually spoken to a guy at their support on the phone already, as well as had an extensive mail-correspondance with another man at Dell. It seems as though they do not know / do not want to reveal which company that makes a particular unit. The link was a comfort in that it tells me there's a slight chance of the 36-LP being the one. Though, the old Cheetah is listed also and I wouldn't want that. There are several Fujitsu units, however I don't know which (if any) of them that are 15k rpm. Thanks for your help!
