The Ninth Amendment was meant as a constriant on federal power - not as a justification for expanding such. If the Ninth and the Tenth are treated as a tandem, as they should be, abortion should have remained a matter for the states. Only by taking an activist view of the Ninth, as happened with Griswold, can such a view be used to supercede both state laws and the Tenth.
The right to privacy became, in effect, a federally protected constitutional right by virtue of the Ninth Amendment and emanations proceeding from several others. The Court does not address any Tenth Amendment concerns in Griswold, and I don't know that any were ever raised.
