Yes, hibernating (or suspend to disk) is much more easy to do than a suspend 
to RAM since you don't need any special hardware. This is simply the kernel 
that detects at boot time that a memory snapshot is available in swap. If 
you're really, really unlucky your video card won't be correctly initialised 
and you won't see anything but normally everything else must be up and 
running (so quite still easy to force a full shutdown).

BTW, a common pitfall once you get use to hibernating is to forget to reboot 
after a kernel upgrade. In my case, grub always chooses the last version 
which doesn't recognise (sigh) the snapshot and do a cold boot (Bug #76424).
