Gotcha! That's exactly what I was hoping for. It does not mean we've
solved the issue yet, but we can definitely rule out a problem with the
ike daemon at this point. It's most likeley your kernel configuration
which is missing an configuration option. Have you hand-rolled your
kernel or used the Gentoo-supplied version of the .config?
I have the feeling -- don't know why -- the IV-generator is missing.
Can you post your kernel config? And the LKM-option I posted before,
might still give us a clue what's missing.

Cheers,
Thomas
