Yes, parse-headers.pl, kernel_include.py and media/Makefile are needed
for one feature ... not very straight forward.

If it makes sense to migrate the perl scripts functionality to a
Sphinx extension, may I can help ... depends on what Mauro thinks.

BTW: parse-headers.pl is not the only perl script I like to migrate to py ;)

Yes, e.g. with "make O=/tmp/kernel htmldocs" the parse-headers.pl output goes 
to /tmp/kernel and is included by ".. kernel-include: $BUILDDIR/xxx"
