I would actually say that it is a chicken/egg problem. Microsoft has made software for x64, but many hardware manufacturers will not spend the time/money to develop drivers since people running x64 is still a minority. So until more people are running x64, driver support will be hit or miss (unless you are using the in-box drivers).
