If you want to use DDEKit, you'll need to provide the interfaces that
it expects or port it to use some other interfaces.  As much as
possible, I'd suggest the former approach as it makes using futures
version of DDEKit easier.

Whether you provide the interfaces in the kernel or in user-space is
an orthogonal question.  The latter is safer.  Given the experience
using the glue code and Linux drivers in GNU Mach, this is a real
day-to-day problem.  On the other hand, providing the intefaces in the
kernel may make it easier to get a system initially up and running.
