Ah, you mean suspend to disk, or hibernating. I was thinking simply of
spinning down a disk, but I have only succeeded with auxiliary disks, not
the one holding root.
On the other hand, I routinely hibernate my computer to disk, instead of
halting the computer to power it off. It works very well for me, and it is
way faster than halting/booting.

I use gnome, so no kpowersave. I suspend by touching the power button
(holding it for 4" powers off hard). There is also a command to suspend
from the kernel (powersave -U), but it may cause problems as it doesn't do
other things needed before suspending.
There are many options you can change related to this: use the bios, the
kernel, unload modules, stop services... its a kind of black art. I'm not
sure which files hold the configs, things have changed recently, and I
have a very mixed mix.
