Hmmm... on initial thought, I don't know how we can handle this one. I
assumed the WAIs were a one-stop-shop for device identification. I also
thought that they would only match if the functionality and register
maps would be the same.
I'll touch base with Denis on this, perhaps he can shed some light.
