if it is so simple to for pm-utils to fix it why not do it? Crashing
a system just because it may affect only less than 1% of Linux users
is inexcusable.

afaics it is not documented anywhere and fixing it is easier than documenting

There is nothing that is obviously risky about overwriting an image in /boot. 
Also it is not necessarily the same user who hits the hibernate button who 
did regenerate the kernel image.
