ACPI integration

[Pierre Ossman]

New versions of xorg seem to have better integration with ACPI by
talking to either acpid or directly with the kernel. On fedora this
causes problems.

Since fedora uses a graphical boot, the X server will have opened
/proc/acpi/events, causing the startup of acpid to fail. For some reason
it is only opened during the graphical boot, not by the "normal" X
server. So I'm guessing there's a way to control this behaviour.
