Okay, that's good for me.

Sure, just an example of "other stuff". Lock is maybe a better example
as gnome-screensaver (or equiv) can respond to this.

The main problem now is implementation.

1. We use the current hodge-podge of methods now (like sony-pi, toshiba,
asus, raw etc) and define backends for all these modules.

2. We use the raw acpi device like Ubuntu do (exposes /dev/acpi) -- Is
this a long term solution? And this requires a kernel patch that I think
the linux-acpi people are unhappy with, and distros such as Fedora
wouldn't like (due to not being in vanilla kernel).

3. Use the new acpi kernel hotkeys stuff -- not that I really understand
the interface, nor how to use it correctly. Plus I'm not sure how much
of the vendor kernel modules can use this new interface, or if it's
suitable. It all seemed a bit fragile last time I looked.
