Fun thing is that laptop OEMs exposing useful 'value-added functionality' (like custom fan control) via pre-defined WMI ACPI callouts is actually the sensible choice to make.

I've seen laptop OEMs that rely on a custom kernel driver for this, and then if you want to reimplement their pile of 'overly modular everything control suite' you're stuck loading a generic read/write-memory driver which is blocklisted by every antimalware and anticheat solution in existence.

(In addition, it seems some WMI/CIM/MOF ACPI stuff is supported on Linux fine, too, as long as OEMs try to stick to standard DMTF-spec stuff I guess... so one can also just do 'generic' user-space stuff there if lucky)
