Integrating OS power management with the X server

I am the FreeBSD ACPI maintainer and recently someone brought to my
attention that the X server expects notification/control over the
suspend/resume process. This event is implemented in this file:
This interface works for apm (except that it only has NetBSD defines
currently) but is not implemented for ACPI. I'd like more information
as to what the X server actually does with this event. Is there any
situation where it actually needs to veto a suspend? Does it
potentially take seconds to save state? Does it need to access other
running subsystems or is it self-contained?
I've started by adding some compat defines for FreeBSD, in the attached
patch. Please let me know more about the expected semantics of this
event and any caveats.
