uswsusp (user space software suspend) has been added to the Debian
unstable archive [1] lately. It works with kernel 2.6.17 and greater and
is imho definitely worth a look.
It doesn't require kernel patches and has some additional features over
the in kernel swsusp like image compression and encryption. (The current
Debian package has disabled encryption support because it formerly
required libssl but is now possible to compile against libgcrypt. I'm
sure updated packages will follow soon).

The first tests I did were very promising. I had reliable STD
functionality and the speed was slightly better than with in-kernel
swsusp (encryption and compression works fine too)

As Matthew already pointed out, the cause for non-working STD is not so
much a case of swsusp or suspend2 but more the surrounding suspend
scripts, which unload/load problematic kernel modules, reinit video
hardware, etc.

I like the small size of uswsusp and think it's the way to go. Following
the discussions on lkml, the inclusion of suspend2 in its current form
is very unlikely too but time will tell.


Cheers,
Michael
