My first thought was that this might be very hard to do - after all the 
system is quiescing everything and swapping it out to disk, and you can't 
have anything mess with the memory image after it starts the hibernation 
process - but then I remembered that in the very earliest days of ACPI 
hibernate, there used to be text-mode progress indicators.  It used to tell 
us where in the hibernation process it was, and how many pages it had 
written to the swap file - plus a useful indication of why it failed to 
hibernate, in the (then frequent) cases where it didn't work.  Now, I fairly 
regularly hibernate when I leave work, only to find that the PC has been 
running in my backpack all the way home - and no diagnostics.
