Thanks a lot, John and Giorgos for those answers, I didn't expect so precise instructions. :)
For the "inflicting damage" part, I was able to crash my system twice using acpiconf -s n, and completely trashed /var and probably some stuff in /usr/lib, unintentionnally, of course, so that kinda forces my hand here. :) Your good counsel shall be of much use! I will put 5.0-release world to the test of rm'ing most of /usr/ stuff. I can always use the CD, in case of complete catastrophe. :) I'll post back results of all this once it's over, along with panic data (no crashdump, yet) from the acpiconf crashes. Thanks again, A.
