As to packaging:
http://fedoraproject.org/wiki/Packaging/Debuginfo

Also of note, needed is:
%defattr(644,root,root,755)

"Kernel modules shall not be executable -- but they need to be after
%install to allow /usr/lib/rpm/find-debuginfo.sh to strip them."

So it's possibly the case that this would work:
