Work is underway to provide facilities to run g-p-m, nm-applet and the
likes when no one is logged in but it's not going to make FC6. With this
we should also be able to display a small power icon, networking icon
etc. on the login screen etc. etc.
That said.. I think acpid just needs to be removed from the distribution
(acpid is fundamentally flawed in many ways) and for the time being
(e.g. until g-p-m will run when no-one is logged in) we could ship a
very small daemon to enforce policy for e.g. powerbutton presses. if
g-p-m is not running (could use a nasty trick to grep the process
list :-). It would of course listen to HAL events and if you write it in
python it would be something like 20-50 lines of code. This could live
in pm-utils. Bill?

Hotkeys on laptops is kinda a mess right now. Some work been done in HAL
CVS to emit events but I'm not sure I like that applications should
listen to HAL to get events a'la "pause button pressed". Ideally the
keyboard drivers in the kernel would be smart and listen for the weird
physical interfaces (some ACPI, some SMBIOS crap etc) that laptop
hotkeys are on and just emit keypresses using the existing input event
