Good, glad you got it sorted out - in fact, I couldn't reproduce the
problem.

I'd just like to mention this to Barbara: I don't think there is any real
problem with using \usepackage inside style files.  Indeed, in my MiKTeX
setup latex.ltx contains the following: \let\usepackage\RequirePackage.
Also \RequirePackage works fine with options passed directly inside [].  As
far as my understanding goes (which isn't always that far!) the thing of
passing options is to allow your package to be called with options, which
can then be passed on to other packages.
