Damnit, I of course had some new problems with the shader... These occur when you use reflection or transparency (which you most probably will when you use anisotropic highlights...). I believe I already have the solution, but I´ll have to "investigate" a little further. Oh, plus you have to use a good render quality ("Quality over speed" for example), or you´ll get huge "artefacts".
But since nobody has even answered me on this one, I assume that nobody has come to these problems... Come on people, has anybody even received my email? Why is it so quiet whenever I post something about new shaders? Shouldn´t at least SOMEone say at least something like "Interesting."?
