Given the simplicity of gif(4) IP-encapsulated packets, I wonder how Linux guys could have implemented something else in their IPIP module :-). I never set up such a tunnel between Linux and FreeBSD myself, but from what I read [1], it seems to work well. Please, would you keep us informed whether this setup works for you or not, it would be certainly worthwhile for the archives.
