If your device did not loose power during s2ram, it should just work.

There's a tweak you can set in /sys you can set if your device is not
removable, you can set it for non-removable devices that _do_ loose
power.

Besides, it seems to break suspend/resume of printers, and probably
all the drivers that do not have reset_resume() method. That's
actually a regression.
