Well, is that really correct?  Stefan??

He probably meant that the s2ram _whitelist_ is going to be deprecated, which
didn't mean s2ram altogether.

s2ram is pretty useful anyway, as it combines many mechanisms that allow us to
bring the video back to life from the user land, so you can use one binary
instead of a bunch of different programs with different command lines etc.
