PM is back with even more new twists.

Last night i upgraded a kernel and without any more thought continued 
working and finally put my laptop to hibernation. This morning when 
resuming i got an error about version difference and the laptop booted 
up without resuming.

Although this is not as bad as the last problem, when i ended up with 
corrupted filesystems and all, but this could still lead to data loss in 
user apps.

The scripts should check for a kernel version mismatch, which wont be as 
easy as it sounds. also it would be nice if we could somehow fixate the 
grub menu (or whatever) so that the version we hibernated with is the 
one that gets booted. This mostly applies for ABI changes and kernel 
upstream version changes. Also, one option would be to refuse 
hibernation all together if the running kernel can't be found on disk.

Sigh, now i spoiled someones morning..
