Now in December 2013 the best available SSL config with a 4096 bit RSA Key and httpd Apache 2.4.7 with OpenSSL/1.0.1e.

YES Windows XP is no longer supported with this. But for me there is no more need to do so.

ssl test lab result

The SSL Test Lap Test shows a very good result. The Cipher Strength is at 100%. So any browser will use a 256 bit encrypted connection to that server.
