If so, it does work, but from time to time you have to shut down your machine. Also, keep a boot option to bypass "hybernate state", since it can save you someday.

I had uptimes of several days, using only the notebook batery with it (no GNOME support by the time), but following above rules prevented a lot of headaches.

If you use too many services (i.e. deamons like httpd, ftp, ssh or so) it does not save much of the boot time, since it is safer to stop/start this services even when hybernating/sleeping/suspending.

I think it is software suspend. The option simply "showed up" someday, after updating my system.

Oh, and thanks for the tips. I'll try keep it running this way to see how much time things go 'till falling apart. :)

Please, keep me updated of the problems you found.

Software suspend seemed to have a "good enough" future by the time I used it. If it's more stable, I want to give it a try.

Good luck.

Is there anything GNOME specific in it? (Just curious, really -- I figure some session management tricks could be employed to further optimize this.)

I don't think. I just mentioned GNOME 'cause it is where I saw the option -- nothing else.

It is probably software suspend.
