Hi! Crazy idea... could we kill hibernate_ops-like struct, and just create a device for ACPI, using its suspend()/resume()/whatever callbacks to do the ACPI magic? > Okay.

It is essentially powerdown_but_enter_S4_instead. I guess we can live with if()... as we need to special-case reboot in the same place. > (4) finish() - called after the image has been restored, do what's currently > done in pm_finish() platform (?) device .resume() method should work.
