Good to know. It sounds like there needs to be some sort of on-the-box mechanism that can gather the required info to automate keeping the HAL whitelist up-to-date, and some checking to make sure that the HAL component that actually invokes pm-suspend and friends is passing flags based on all that knowledge.
