I don't know either which ratio of visitors this represent.
My bet is that it's around 10-20% but I have no data to prove it.

My main concern when dealing with this issue is cost-effectiveness.
I really appreciate all your ideas but they would represent a loooot
more work than improving the current web page to prevent at least part
of the confusion. So I'll try the cheaper versions first and escalate to
something more elaborated only if needed.

For the time being I changed the page to display both addresses when
the future (as this behavior is also quite new).

That would work for people who know OpenPGP. I'll keep this in mind if
the issue is raised again in the future. For the time being, HTTPS is
enough for *us* to trust that the correct bitcoin addresses are
displayed to all the people who wouldn't do through the extra step of
verifying them using OpenPGP (the vast majority I guess).

Namecoin sounds cool but I'd rather wait until it becomes more mainstream.
Thank you for following up!
