Sounds about as easy as hot unplugging arbitrary memory address. IOW "not easy".
Regardless, forcibly panicking the system more is still the wrong
approach IMO.
Instead, I'd try to issue a big fat warning that BIOS corrupts E820 and
that the user should disable hibernation on that box and never ever
enable it again.
After that, the kernel should *disable* hibernation for the current boot
so any further hibernation runs don't even happen. Maybe even taint
itself.
