Yep, you work around this one by enabling polling. > This faking out the user, plus the fact that the BIOS does change > trip-points at run-time, made the original scheme fundamentally > unsound. Further, I've not yet found a single system where use Yes, this one is uglier. But maybe "enable polling automatically + ignore any updates from bios" (+ maybe "only enable lowering") is better solution than "just remove the knob"?

This is okay as long as you are willing to work around the fundamental problems in kernel. You are unable to _fix_ them. They are broken BIOSes.
