The "SOFTWARE SUSPEND" entry in MAINTAINERS already contains a victim...  ;-)

My impression is that suspend is an area of the kernel that does not 
lack maintainers - you and Rafael are doing a good job, and there's e.g. 
also the maintained code formerly known as suspend2.

But some basic questions like e.g.
- What should be done in the kernel and what in userspace?
- How should this be implemented?
- What must subsystems and drivers do?
- What must subsystems and drivers not do?
seem to be in a constant flux because the big picture everyone agrees 
upon seems to be missing.
