The "hard work" means you can not use the Windows DDK at all. People
have worked to reimplement the header files needed for this into mingw,
but it really restricts you and forces you to write "native" drivers for
Windows, not being able to take advantage of their driver model code at
all.

Oracle did a bunch of work for this in the past to port some of their
Linux kernel work to Windows, ask Andy Grover if you have questions
about it.

hope this helps,
