Ah! Ok, sounds like a misunderstanding.

For the background this is *not* a new device id, but rather changes the
way the existing device ids are discovered.

Instead of a table with device ids and hard coded list of hw blocks
inside a device, we now look at a VBIOS table to determine which hw
version/blocks are present.

So yes, this might enable new hardware but it's most likely not trivial
enough to be backported.

Alex, that is mostly a question for you.
