Got confirmation from Windows people. So Windows pretty much saves and
restores the same registers than we do (padcfg + ie).

Have you tried whether s2idle works instead of S3 suspend? You can try
it like

# echo freeze > /sys/power/state

If that works, I'm guessing that this system uses s2idle and that's also
what Windows uses and could explain why it works in Windows.
