Unfortunately, the HTTP_USER_AGENT is not a good way to identify browsers, despite 99% of dot.com business sites that think they can. This is easily faked and could also change if the user is behind a proxy. If you really need to , you can try to match with m#Mozilla/4\.\d#, but do it with full understanding of mislabelled browser.

A better question to ask yourself is why you need to disable CSS for NS4 browser. Yes, I do know that NS4 (paricularly before 4.5) does have some CSS oddities, but a lot of them are a result of poor web page writting or or CSS set up. While it's outside the scope of PM, it might be helpful to know what CSS NS is choking on.
