> I would guess that the number of owners of consumer chips who also relied on them for encryption is exceedingly small.

I guarantee you that there's one small company that put 1,000 of these chips in a server room or datacentre though, and they're now completely boned.

In that case I would expect them to try and work something out with AMD directly instead of building a company on undocumented features.

Just dont upgrade the Mainboard firmware then
