TLS: How to detect if a browser supports it?

Our website has an SSL certificate installed by TrustWave that is causing browsers without TLS security enabled, to fail.

This just started happening today (July 3, 2010). Our concern is that visitors to our site will not be able to purchase products because their browser will fail to load the page (there is no error message indicating that's the problem when using FireFox, IE does hint at it if you expand the diagnostics but how many users would understand it?)

QUESTION: Is it possible for our website to detect is a browser does not have TLS enabled before they get to our secure page, so that we can warn them in advance?
