I have to admit, I haven't really looked at how other architectures
are overriding the domain building stuff. Would it be possible to
override xc_dom_linux_build to grab the couple of extra parameters
you need (cmdline, features) from dom and pass them to your existing
xc_linux_build? Then you can pass back elfnotes to python at your
convenience, if/when it makes sense.
