[iaik-ssl]cu|| 40 vs. 128 bit certificate question

I'm trying to figure out what the (technical) difference is between a 40 
and 128 bit certificate, like verisign is selling.
What is the actual difference between a "40-bit SSL Secure Server ID" 
certificate and a "128-bit SSL Global Server ID" certificate. As far as 
I know, there is no such thing as a keylength limitation in a certificate.
When my server application supports 128 bit encryption, and my client 
application, too, I don't think that my 40-bit verisign server cert can 
prevent the use of 128 bit keys?

In other words, why should I buy a 128 bits cert, which is more than 
twice as expensive as a 40 bit cert.

Can anybody clarify these things to me?
