I'm not sure that I understand what you are trying to do. 
#include <linux/foo.h> and #include <xeno/foo.h> should mean the same
thing when building Xen -- all kernel object files should be built
with -nostdinc, and incude/linux is a symlink to include/xeno.

When building Linux for Xen, it does not use any Xen headers except
those in include/hypervisor-ifs -- all other headers are private to

It sounds like you may be spending time on something that isn''t
broken. :-(
