Suspend-to-disk.  It's disabled by default for some reason in Fedora
kernels, but Linux supports it.

You can, depending on your BIOS and age of your machine, use BIOS features
to do the same thing without resorting to kernel patches/recompiles.  I
use my Thinkpad X22's BIOS-provided suspend-to-disk function for this.  

On laptops, this sort of functionality is essential.  A full boot
from scratch costs lots of battery power.
