hmm, i inspected the core files today and saw the filenames are fixed inside the frontend-functions-file... too bad...
i thought about overwriting a function somehow first inside the view.php, but i saw this stuff is not part of any function and the function calls take place before the template gets loaded.
i wanted to keep it the most flexible and be able to switch it all from the module 'view.php' without taking care of the template...
but i guess i am going to fix it the way you suggested ruud.
btw.: have you tried this PHP script?
http://www.conditional-css.com/advancedthe script checks the user-agent string and you are able to fix tricky CSS behauviour on complex sites easily.
all the best,
