IPSec (FreeS/WAN) not in kernel-sources

Hi all, I use SuSE 8.0 and saw that it has the compiled kernel module for IPSec (FreeS/WAN). That's fine. Now I wanted to compile my own kernel (no module support for higher security) but saw that it lacks the FreeS/WAN code. The ipsec.c is not there. So my question is if that's normal or do I miss something? It's not a big problem, because I alsways can manually patch the FreeS/WAN code into the kernel, but I just found that strange. Also makes me wonder what else is in the kernel binary and not in the sources. Cheers, Stephan -- I intend to live forever. So far so good.
