That's different.
I don't know where these patches are leading, but thus far they look like
reasonable cleanups and generalisations. So I suggest we just take them
one at a time.

uswsusp seems like a bad idea to me. We'd be better off concentrating on a
simple, clean in-kernel thing which *works*. Right now the main problems
with swsusp are that it's slow and that there are driver problems.
(Actually these are both driver problems).
Fiddling with the top-level interfaces doesn't address either of these core
problems.
Apparently uswsusp has gained support for S3 while the in-kernel driver
does not support S3. That's disappointing.
