I found 'OpenFileById' and 'GetFileInformationByHandleEx' in Kernel32.dll and it says "WinBase.h (include Windows.h), FileExtd.h on Windows Server 2003 and Windows XP".
So it appears we could get it to work on XP and Server 2003 by creating a dll for FileExtd.lib. I'm using NtCreateFile, ... for now.
