The idea of using the Launchpad PPA to provide deblobbed versions of Ubuntu
kernels was also suggested by someone else, since having two repositories
both providing the latest version seems to be a duplication of effort.
However, there was some thought that rather than provide deblobbed kernels
for Ubuntu users it might be better to instead encourage them to move to
something like Trisquel instead where they get not only the free kernels but
everything else free too.
Either way I'll discuss it with DNS.
