I am attempting to get uswsusp working on my Debian Sid machine. After reading the docs, a couple of SuSe web pages (http://en.opensuse.org/S2disk) regarding s2ram and s2disk I am stuck on one detail: CONFIG_SOFTWARE_SUSPEND=y. I can not find this kernel option anywhere when attempting to configure the kernel. Whether it's the debian 2.6.18 source or the kernel.org 2.6.20 source; can't be found. Not under the ACPI options, nor the CPU frequency scaling options.
Attempting to dpkg-reconfigure uswsusp results in:

Your kernel doesn't support userspace software suspend Your kernel doesn't support userspace sofware suspend. Please reconfigure your kernel to include
    CONFIG_SOFTWARE_SUSPEND=y and recompile.

Can someone point me in the right direction?

In 2.6.18, it's under 'Power Management Options'. Check 'Software
Suspend'.

No. It is not. That's why I went to the trouble of downloading 2.6.20 from kernel.org. These are my options in either kernel:
[*] Power Management support
? ? [*] Legacy Power Management API (DEPRECATED)
? ? [ ] Power Management Debug Support
? ? [ ] Driver model /sys/devices/.../power/state files (DEPRECATED) (NEW)
? ? ACPI (Advanced Configuration and Power Interface) Support --->
? ? APM (Advanced Power Management) BIOS Support --->
? ? CPU Frequency scaling --->


And under ACPI:

[*] ACPI Support
? ? < > AC Adapter
? ? < > Battery
? ? <*> Button
? ? < > Video
? ? < > Generic Hotkey (EXPERIMENTAL)
? ? <*> Fan
? ? < > Dock
? ? <*> Processor
? ? <*> Thermal Zone
? ? < > ASUS/Medion Laptop Extras
? ? < > IBM ThinkPad Laptop Extras
? ? < > Toshiba Laptop Extras
? ? (0) Disable ACPI for systems before Jan 1st this year
? ? [ ] Debug Statements
? ? < > ACPI0004,PNP0A05 and PNP0A06 Container Driver (EXPERIMENTAL)
? ? < > Smart Battery System (EXPERIMENTAL)
? ?


Now, the only thing I can think of is in regards to the error message I get whenever a new version of uwsusp get installed, which is:

Configuring uswsusp
?
? Your kernel doesn't support userspace software suspend
?
? Your kernel doesn't support userspace sofware suspend. Please reconfigure your kernel to include
? CONFIG_SOFTWARE_SUSPEND=y and recompile.
?
? <Ok>


So, how come software suspend is not listed under my kernel options??
