SSL and negotiated key strength

Greetings all, I've been playing around with SSL and Certificates and have come across a problem. I'm using apache and IIS as the web servers, and for an example IE5 with 56bit capable encryption. This is what I am seeing: (1) With a global certificate, 128 bit shout be enforced, and for all browsers that do not support 128 bit, the browser is "stepped up" somehow. - With my 56bit capable browser, only 40bit encryption is negotiated, not 128bit. - With a 128bit browser, 128bit is supported. Shouldn't it be the case that 128bit be used for all browsers with Verisign's Global Certificates... ? I shouldn't have to define in apache or IIS to force 128bit, or should I? I am wondering whether the option in IIS, for example, to enforce 128bit, only permits browsers with the high crypto pack installed on the client? (2) Connecting to Fortify.com, the SSL test for a 56bit capable browser only negotiates to 40bit, why does it not use 56bit? I believe that 128bit crypto can be exported now, please correct me if I am wrong, and hence outside connections using SSL with 128bit encryption is legal? Cheers r.
