I just stumbled across the Design Scenarios for Linux's Power Management
Quality of Service system, courtesy of Intel. [1]  Notable inclusion:

# Platform Suspend
    * you can put the system into S3 or S4, as a function of acceptable
wake up latency
    * you can specify the delay in dropping into a suspend state as an
idle time out

I don't know exactly what this means, if anything, but it sounds good.
