With Openswan 2.3.0, there is experimental support for the KLIPS stack 
(provides the ipsec0 interface) on 2.6 kernels (even if they have the 
26sec stack enabled.) There are, however, a few caveats:

1) NAT Traversal will not work. The NAT-T structure in the kernel has 
changed with 2.4/2.6, and the KLIPS code has not been updated to deal with 
it yet.

2) 2.3.0 has some nasty bugs; wait until 2.3.1 comes out for production 
systems.  :)
