CONFIG_SOFTWARE_SUSPEND

Hi,

I started to have some look into how S3/S4 work with 2.5/2.6 to
(hopefully) resolve my S3 problems. Now I stumbled across the following
in drivers/acpi/s

#ifdef CONFIG_SOFTWARE_SUSPEND
	case ACPI_STATE_S2:
	case ACPI_STATE_S3:
		do_suspend_lowlevel(0);
		break;
#endifleep/main.c:

To my understanding swsusp is some non-bios-supported method to realize
S4. This view is given as well in kernel configs help text. So why do
S2/S3 depend on swsusp? And CONFIG_ACPI_SLEEP as well?

Sorry, if this is too stupid.

Regards
