I'm afraid you cannot do this "in an automatic fashion" without
knowing what to expose as RDF actually.
For me there are three poeple with real clear incentives:
1. news corps and those bigger publishers who already have their
developers or can pay some to do that mapping (BBC)
2. research orgs, NPOs, NGOs, also GOs which publish public data
(EuroStat, US census)
3. nerds like us ;-)
But any other people like bloggers, etc. will have to wait until the
nerds have created CMS with RDF built-in (e.g. Drupal), but they won't
be able to expose data they already have in RDBMS without us nerds.

Do you know any solutions that produce RDF Linked Data from RDBMS

Not yet... unfortunately. There are still open research problems:
ontology matching, linking algorithms. All of this is needed to
have such a system.
At what time in the future do you expect such a product to emerge?
When such a system exist, is when we can say that everybody is on
the semantic web. Time... how about by the time I finish my PhD. :P
Well you've just made my point re. Cognitive Dissonance :-(
I don't agree. I am clearly stating a problem, and the paths needed
for it to be solved. How am I contradicting myself?
Ok.. I believe I see where the confusion is. Of course virtuoso and
d2r server publish RDF linked data, etc. What I mean is that it does
not happen in an automatic fashion. That is needed! At least for all
my web developer colleagues who will never invest time in learning
about virtuoso and d2r server.
