I would suggest compiling a small C# assembly which is just something
like:

	public class Maker {
		public static object MakeGraphicsDeviceManager() {
			return new GraphicsDeviceManager();
		}
	}

And then call this instead of calling GraphicsDeviceManager directly.  There's
occasionally a type which disallows being created via reflection/dynamic methods
(for whatever reason) and this is one work around.

Another possibility is that we're calling it via reflection because it hasn't
been called enough but it'll work if called via a dynamic method.  In that case you
can actually call it in a loop until we optimize the creation to a call from
a dynamic method.  I doubt this is the case this time though because of the 
error message is specifically calling out the dynamic assembly.
