First of all, always try the latest kernel with the latest openswan only. Since
the kernel changes API every minor release, you WILL need that. So you should
have used openswan 2.4.7, not 2.4.6. Next, some of your fixes have been addressed
already and are in CVS. The reason we have not released this as 2.4.8 is that
we are still crashing the kernel in NAT-T mode, and we're still figuring out
why. Until that's fixed, we cannot release a new version that supports 2.6.19 or
2.6.20.

I will look into this issue, I hadn't noticed this yet.

Those fixed are already present in 2.4.7.
