Userspace Software Suspend is an alternative to the default hibernation method in the Linux kernel. It adds several interesting features like compression, encryption… Compression allows for hibernation with a smaller Swap partition. It also decreases the wake up time of your system!
Here is how to install USwSusp on Ubuntu Karmic. Should also work with a recent Debian.
Install the uswsusp package:
aptitude install uswsusp
You can now hibernate with the s2disk command as root.
To hibernate from Ubuntu menu or by key shortcut, then change the following line in the /etc/pm/config.d/00sleep_module file:
SLEEP_MODULE=uswsusp
And test your hibernation!!

I guess this does not matter now but i think you wanted to say:
“It also _decreases_ the wake up time of your system!”
because of slow IO of the disk
Thanks for the correction!
I corrected my mistake.
My english is not perfect..
Thanks. I discovered uswsusp while playing around with antiX and a couple of other Debian Testing/Unstable-based systems. Glad to see it works on Ubuntu Lucid, this is the fastest resume-from-hibernation I’ve ever seen on a *buntu box.
how do I install the uswsusp package on debian squeeze for raspberry pi . i have tried aptitude install uswsusp but i got an error mesaage `no candidate version found for uswsusp`
It appears that the package is not available in the actual Debian stable (squeeze) :
http://packages.debian.org/search?keywords=uswsusp
Maybe try the wheezy (testing) version.
