Now the latest version of Apache mod_ssl (2.2) embeds an option to reactivate old way client renegociation :

SSLInsecureRenegotiation on

Check the official doc for more details. With this option activated, you can now safely upgrade openSSL and mod_ssl without breaking your clients. They should have done it from the begining, shouldn’t they ?
