They should fix ACPI systems, if they don't we need to fix them further
- that case should just work, it was an oversight not to have a patch
like the ACPI one in already.  I'm not sure how many non-ACPI PCs still
exist, we're definitely talking about things over 10 years old (even
before PCs became ACPI only they started to have ACPI present which
should be sufficient).

Jean, I'm doing a writeup but it's probably not going to be done today.
