CONFIG_SOFTWARE_SUSPEND=y, ACPI, and uswsusp

[Nick Lidakis <nlidakis@verizon.net>]

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?

By the way, the hardware is an Asus A8N-SLI desktop motherboard.

Thanks.
