You would need to set it in /etc/sysctl.conf.  Alternatively,
could add code to parse the loader versions to the code in acpi.c
that sets the initial values:

    sc->acpi_power_button_sx = ACPI_POWER_BUTTON_DEFAULT_SX;
    sc->acpi_sleep_button_sx = ACPI_SLEEP_BUTTON_DEFAULT_SX;
    sc->acpi_lid_switch_sx = ACPI_LID_SWITCH_DEFAULT_SX;
    sc->acpi_standby_sx = ACPI_STATE_S1;
    sc->acpi_suspend_sx = ACPI_STATE_S3;

Also, you could patch acpivar.h locally to set ACPI_LID_SWITCH_DEFAULT_SX
to ACPI_S5 + 1.
