Thats a good start :-)

You can follow the same procedure exactly, but getting the support
under uClinux to do that may take a little more work.
If you want to use the "ipsec ..." scripts you will need quite a few
complex tools and a good shell to get the scripts to run.
Also, openswan (AFAIK) has never been run on uClinux. The Freeswan
version in the uClinux-dist has been used under uClinux.
You will need to clean up any "fork" code in openswan as a minimum.

Use the "whack" command to get information from the IKE daemon (pluto).
Other than that, not sure what kind of info you want. There are ways
to get most information without writing any fancy new code,
