Actually, prethaw is to prevent drivers loaded before the image is restored
from doing unreasonable things. It doesn't have any effect on the drivers'
.resume() routines.
Besides, if the drivers in question are compiled as modules and not loaded
before the image is restored, prethaw doesn't have any effect on them and
on their devices at all. ;-)

Yes.
