A while back I suggested checking the last mount time of the mounted local
filesystems as a quick and dirty sanity check between loading the image and
unfreezing all the processes. (Since a read-only mount shouldn't touch this,
triggering swsusp resume from userspace after prodding various hardware
shouldn't cause a major problem either...) Does that sound like a good idea?

Haven't had time to look into it myself, though. (Just recently got time
enough to bang on busybox again. Somewhere around 2.6.7, software suspend
stopped working for me and I haven't even had a chance to track _that_ down
yet. Hopefully fixed in 2.6.9 or 2.6.10, I haven't played with it
recently...)
