After reading all the other comments, we can conclude that the question is flawed 🙂
You cannot move the resource DB in 2008, but apparently you can in 2005, so the question should have stated the version of SQL Server.
I got it wrong, as I was reading the KB of 2008, I saw the title "Moving the Resource Database" and I assumed it could be moved. Unfortunately I didn't read the fineprint that stated: "The location of the Resource database is <drive>:\Program Files\Microsoft SQL Server\MSSQL10_50.<instance_name>\MSSQL\Binn\. The database cannot be moved."
