diablo@diablo linux-2.6.21-gentoo % pwd
/usr/src/linux-2.6.21-gentoo
diablo@diablo linux-2.6.21-gentoo % cat .config |grep CONFIG_SOFTWARE_SUSPEND
diablo@diablo linux-2.6.21-gentoo %    

Is it normal? I know that swsup2 patches are in the suspend-sources kernel. 
But according to the documentation software suspend v1 should be supported in 
the gentoo-sources.

I moved .config from previous versions of kernel using "make oldconfig".

Using gentoo-sources i got the same problem. You are using SMP, right ?
Then you have to enable CONFIG_HOTPLUG_CPU to get CONFIG_SOFTWARE_SUSPEND 
selectable.

It took me some digging that those two are dependend when doing SMP.

It's not that hard to find

make menuconfig
/suspend

Symbol: SOFTWARE_SUSPEND [=n]
  Prompt: Software Suspend
    Defined at kernel/power/Kconfig:80
    Depends on: PM && SWAP && (X86 && (!SMP || SUSPEND_SMP) || (FRV || PPC32) && !SMP)
    Location:
      -> Power management options
        -> Power Management support (PM [=y])

K: (n., adj.) a binary thousand, which isn't a decimal thousand or even
really a binary thousand (which is eight), but is the binary number
closest to a decimal thousand. This has proven so completely confusing
that is has become a standard.

So - can you show me the link to CONFIG_HOTPLUG_CPU here ?

It's not in the rule above. First i tried to find SUSPEND_SMP, but no chance.

Really. Enabling CONFIG_HOTPLUG_CPU helped. Thank you very much.
