I am using a Windows Authenticated user login as a member of the role. I've tried adding the role to the schemas after explicitly granting the role exec permission to the sp with no joy. The proc executes fine when logged in as sysadmin...

 
The user the executes the code against sys.databases will need the VIEW SERVER STATE right. You don't want to give this to all users. You'll want to use impersonation to impersonate a different login which has these rights. Look up EXECUTE AS in the SQL Server Books OnLine (the help file).
