Hi, I gave this a casual try once.  The difficulty is the same 
difficulty you get trying to write Linux kernel modules in C++: 
the Linux build system is a mess of make files that are only 
designed for C, and don't represent a stable API between kernel 
source versions.

If I had to write a Linux module in D, I'd write an interface 
layer in C that gets built using the normal Linux build system 
and can be linked to my D code.  The interface would have to 
provide alternatives to the various Linux preprocessor macros.  
(I think trying to refactor the build system to work with dpp 
would be a total waste of time.)
