Powering off rather than using S4 means you lose most wakeup device

only if the kexec isn't able to initialize those devices.

If you aren't using ACPI, you probably don't know how to.

the current kexec patch to allow you to move back to the original kernel requires ACPI be disabled to work.

that states pretty strongly that kexec isn't dependant on ACPI to initialize devices.
