Suspend to disk?

I'm experimenting with powersaved and uswsusp and not having much luck with either.

Trying to suspend to disk with powersave -U results in a message that I need to add a 'resume=...' to the kernel commandline and reboot. Then it advises to check the documentation which is rather mum and nowhere do I find the suggested SUSPEND2DISK_SKIP_RESUME_CHECK option so I can set it to "yes".

So, I then tried the s2disk program from the uswsusp package and it suspended to the swap partition without complaint. When I powered the machine back up using the same kernel as when I suspended it, it booted normally except that it couldn't find a swap signature on my swap partition. Well, duh, my suspended image was there! So, I would up doing a mkswap and swapon -a to restore it.

So, one method won't suspend and the other won't resume. Go figure! I understand that I probably need to pore through the docs more, but the uswsusp.conf file is deceptively short.

Not that it matters right now, but this is on a Thinkpad T23 with 800 MiB of swap and 768 MiB of RAM. As of the latest experiments I'm running an ancient 2.6.18-4-686 kernel on Sid and I plan to install the latest 2.6.22 shortly. I do use the Debian packaged kernels.
