AFAIK GNOME uses the HAL/Dbus solution and it works quite well. I
belive KDE should support the same, even though it can has other ways
for same thing. If they does not, then when you press the Power Button
(and the ACPI event is raised) it won't know about it (well, it can
know if it duplicated the acpid functionality  but I doubt the would
do it).
