Definitely is a big word, I've looked at the DMI parser currently in the 
kernel, tried to come up with a way to get the info there which would be more 
generic then just being an fschmd specific hack and couldn't. Then I slept a 
night on it and still couldn't come up with something clean, esp since there 
are many type 185 entries in the DMI table of FSC machines, of which we need 
only one.

That indeed has been ackknowledge by my Siemens contact.
