    I've tried acpi_sleep=s3_beep, and this:

    diff --git a/arch/x86/kernel/acpi/realmode/wakeup.S b/arch/x86/kernel/acpi/realmode/wakeup.S
    index 3355973..50e50df 100644
    --- a/arch/x86/kernel/acpi/realmode/wakeup.S
    +++ b/arch/x86/kernel/acpi/realmode/wakeup.S
    @@ -37,6 +37,11 @@ signature: .long 0x51ee1111

    wakeup_code:
    _start:
    + movb $0xC1, %al
    + outb %al, $0x80
    + cli
    + hlt
    +
    cli
    cld


    Which doesn't work either.
