I fired my distro's ACPI event-handling code. Several years ago it started being not merely useless, but an active source of failure. After several rounds of patches that consisted only of deletions, I gave up and replaced the entire thing with:

#!/bin/sh
echo mem > /sys/power/state

I have "find out where the acpi-support package is hiding today and kill it" on my to-do list for every dist-upgrade because the machine can be physically damaged if I don't.
