I wrote such a patch to support another kind of tunnel interface (teredo
ones using miredo, but it also works over 6to4 tunnels). I never had a
chance to test with a ppp interface.
You can grab it using mercurial by simply cloning the repository:
$ hg clone http://hg.natisbad.org/migrate2_patches_umip_nemo
destination directory: migrate2_patches_umip_nemo
requesting all changes
adding file changes
added 52 changesets with 135 changes to 27 files
14 files updated, 0 files merged, 0 files removed, 0 files unresolved
The one of interest in the folder is "tunnel_support.patch". Note that
the folder is in fact a quilt set, and that patch (as described in
"series" file) applies on top of almost all others. Applying it directly
will probably fail but you should be able to adapt it easily.
Don't hesitate to ask some help if you do not succeed or need some
comments on the patch.

after applying the patch, read the modified man page, and smile ;-)
