The group that does a lot of the polls that are published in French papers is TNS-SOFRES. Their web site has a section on politics and elections (2nd left hand menu item) under which you can find polls about political candidates and parities as well as polls on policy issues etc... The FN political party polls are in the political party section: http://www.php.sofres.com/cote3 . So far this year (2006) 10 to 11% of poll respondents had a favourable opinion of the FN and 79 to 80 had a negative opinion of the FN.
