CONFIG_ACPI_PROCESSOR, because it allows deep sleep states with
significant wakeup latencies.

But back to your original issue: You mean your notebook booted fine
under vanilla Linux with ACPI disabled? That would mean I-pipe relies on
ACPI here without stating this anywhere. In that case /something/ needs
fixing: code, config deps, or doc.
