Additional tests show that IsValidDevmodeA/W actually does a lot more than I previously thought.
Implement the missing known features and test this little function to death in winspool_apitest to cover each and every possible call.
They pass on ReactOS, Windows Server 2003 and Windows 8.1.
Credits and many thanks go to Mark Jansen for the additional tests!
