Make suspend to disk dumb-proof

Bug Description

Binary package hint: acpi-support

When hibernating, Ubuntu does nothing to make sure to boot next time the same kernel. It can lead to loss of data if incorrect kernel is booted. In my opinion, Ubuntu should make temporary changes to grub configuration that would
- disable menu
- set up timeout to some sensible value (not to waste time but leave space for corrections if something goes wrong)
- make running kernel image option default (either through save default or explicitly stating it)

and revert these changes after waking up of course. AFAIK OpenSUSE does something like this.

Regarding this matter, it would probably be better for a hook to be
included in the grub package.
