This is what I was getting at in my other post.  I'd sort of rather that 
a certain set of SMBIOS tables be specified at a higher level (like 
uuid, manufacture, vendor, etc.) and the blobs just be the OEM tables.  
I think that matches the work going on with the device configuration 
files more appropriately.
