That's strange, since I've compiled openswan-2.3 on many 2.6 kernels.
How are you compiling? Are you patching the kernel, or are you using the
out of tree building setup?

the latter is recommended. On a non-openswan patched linux tree, do:
cd openswan-2.3.x
make KERNEL_SRC=/usr/src/yourlinux-2.6/ module26
(this won't work if you already manually patched that tree)

You you did patch the tree manually, try:
cd /usr/src/yourlinux-2.6
cp .config /tmp 
make mrproper
cp /tmp/.config .
make oldconfig
make bzImage modules modules_install
