there is contradictory information about how much work needs to be done for the restore
the current restore functions assume that all the hardware has been put into ACPI low-power mode or the restore image may not work
so the two options right now seem to be
enhance this mode
use kexec to do a kernel shuffle (boot one kernel, kexec to a second kernel that's in the reserved space, then restore the image to the origional location (overwriting the boot kernel) and then kexec into it
the second approach isn't elegant, but doesn't depend on the state of the hardware.
