Sounds plausible. This needs to go in the changelog.
A lot of their K8 chipsets were also used on P4 (I think they
abstracted the architectural differences with V-Link), but
if they claim this wasn't used on any of the P4 boards,
I guess they would know better than us.
(The irony here is that the cset that introduced that ID came
from a patch where someone copied a giant diff on one of VIA's
earlier portals).
