  Ok my motherboard patch was dropped from -mm so I am broken again but
others are fixed. Is the answer that we do nothing about this issues?   

  I am pretty sure my SSDT table is valid if someone *cannot* point out
in the spec where my device is malformed  by having both HID and CID I
will not be able even start the request to change the BIOS (it would be
a waste of my time).  Sure having the CID of the memory device may be
overkill but is it wrong?  

  Unless someone can show me a alternate solution I am going to push the
check HID before CID patch to -mm in the next day or two. 

Thanks,
  Keith
