I'm also not sure.

To be clear, my desire to see a test that triggers only for the Intel
chips with the problem, and is written in a way that matches exactly
the ACPI data from the broken chip - so things like !CRB are not what
I want to see..

In that light the example I gave was probably not well thought out,
but I also do not understand the exact conditions needed for the Intel
work around either. Hopefully Jarkko can clarify.
