es, indeed, there is a chunk missing, so this patch is incomplete. It
will not cause any issues if applied, so I'll leave it to Greg to decide
what to do with this.

Vincent, there needs to be a change in trackpoint_start_protocol() to
mark these new IDs as valid. Was it s3ent in a separate patch and I
missed it?
