There will be a prize for the first person to find a way round that, it is

An additional note: Apparently, the person who produces Speedfan is ready to
change the latest beta into the operational version. He wants to sign the

anything about how to sign drivers with certificates, you might consider
commenting on his blog: http://www.speedfanblog.com/
