I'm marking this as confirmed, as this is a problem, but it could just
as easily be marked rejected (more or less working by design), because
the underlying design is problematic. Of course rejecting it would
simultaneously require a blueprint be opened to cover the following....

The problem is that we have multiple conflicting ACPI event management
tools on laptops. The proper set includes HAL and PMI, which are used by
Gnome (comments about limited power management capabilities in gnome
withheld), and these apply to all machines.

The conflicting set is laptop-mode tools and various ACPI event scripts,
which - by design - are not used when Gnome is running (scripts contain
checks to silently exit and let Gnome handle policy).

This is counter to what the user expects. The correct things to do are
all of:

a) provide script-level PMI controls so that users can
suspend/resume/etc. from scripts if they so choose,

b) remove the laptop-mode and other tools obsoleted by PMI and its
brethren, and

c) give Gnome more configurability, so users can make their machines
behave as expected.

That's a lot for one report. Unfortunately, I am no longer able to
triage, so that's the best I can do with this. Hopefully someone else
can pick this up and make the right things happen.
