BTW, there is a complete lack of DirectDraw examples out there, especially using Python. If someone has links to such I'd appreciate it, especially those for 3D surfaces. (We're slowly trying to build an accelerated wxPyPlot-like widget that uses OpenGL/DirectDraw - and I mean slowly...)

The Microsoft documentation is misleading; GetMonitorFrequeny and
GetScanLine are not *functions* exposed by the directdraw library.
Instead they are methods exposed of the IDirectDraw COM object.

You cannot access this stuff with stock ctypes.  If you are able
to find a typelibary for directdraw then maybe you can do it with
comtypes.
