Please update as follows:

1) Provide a detailed explanation as to /why/ this is needed.  I certainly encourage use of ahci over legacy mode, but the patch description tells us nothing.

2) Combine the two patches into one.  Think of a patch as an atomic operation.  If you apply your patches as submitted, then a 'git bisect' 
may reach a state where the PCI IDs exist in _neither_ sata_nv or ahci. 
  Any time you /move/ code or data, it should be in the same patch.

3) Your patches are completely unreviewable in a standard Internet mailer, because they were sent with your email base64-encoded.  For many mailers, base64 encoding means the patch is not shown nor able to be commented upon.  Indeed, some mailers make it difficult to response -at
all- to data contained in a MIME attachment.

The change itself seems OK, once suitable justification is provided.

	Jeff
