What do you need to get CVS access to the CSS file? Roberto or I can set that up for you, or are I missing something?
Clearly CSS is the way to go, as much as possible, the trick is to figure out which bits of CSS NN4.x does OK with and which parts it messes up with. We know the result on NN4.x will look more like a drunken homeless old sheep and not a cute little lamb, don't worry about that. I think nearly everyone here has personal experience trying to get NN4.x to behave while at the same time using CSS.
