You can't point to an IP address like that. Will your entire domain be hosted at dreamhost? If so, what you want to do is add the domain in the panel on manage domains, then mirror that to dreamhosters so you can see it and set it up, then change the nameservers to point to dreamhost after it's correct.
If on the other hand you only want the web portion (i.e. not email) pointed to dreamhost, you would still want to add your domain on manage domains, mirror it to dreamhosters.com so you can see it, then when you are ready to point to it, go back to manage domains and click the DNS link right underneath the domain, when the page loads scroll down and look at the non-editiable entries and the first one should be an A-record with an IP as the value, record that IP address then enter an A-record at godaddy point to that IP address.
