are not part of the kernel any more. Both boxes are running 2.6.38-8
as compiled by Ubuntu:
# uname -a
Linux ns3 2.6.38-8-generic-pae #42-Ubuntu SMP Mon Apr 11 05:17:09
UTC 2011 i686 i686 i386 GNU/Linux

Next finding:
If I start ipsec (or better restart) it's working, at least for the
gateways themselves. Doing nothing next few minutes, then trying
again --- doesn't work any more! I have to restart ipsec again.

I'm filing a bug now. Hopefully someone digs deep enough too make
these errors vanish!
