I tried to accomplish it on -current, creating the partition etc, but didn't succeed. My conclusion was that it won't work. > Provided you stick to APM.. > The suspend to disk thing is only available with APM - This is not 100% true.

Realisticly speaking I know the change that I will ever finish it is small. Things I did until now are exploring the mechanisms and code to see what would need to be done. I have also looked at the Linux swsuspend implemenation. However, I expect that there is a big need for this which is only going to grow with about all laptops being produced now being ACPI only, and the vendors only looking at Microsoft. That need might attract more people to work on this in FreeBSD.
