"normal activities" being "screensaver and walk away", but I think that's a
good approximation of my normal GPU activity (redrawing the terminal a couple
times per second).

Not sure I feel daring enough to try those patches. Am I supposed to be able to
apply that to 5.3.11 or perhaps compile drm-tip + that as a module for 5.3?
