Unfortunately, Ubuntu in their "wisdom" removed s2ram and claim "s2both" 
supersedes it in that it does both suspend to disk and suspend to ram and 
then suspends, but if your battery dies while suspended you can still 
resume from the suspend to disk.

Right.  I will give s2both a try and see what happens... no joy.  It 
fails to even run without the swap device mounted, and my swap device is 
not big enough to hibernate to anyway.  Damn you Ubuntu.
