A feature to deal with this was just added to the CVS feature branch
based on patches from "Chris G. Demetriou". It is the 'cvs import -X'
switch which may be enabled by default using the option
"ImportNewFilesToVendorBranchOnly=yes" in the CVSROOT/config file.
If you checkout the top-of-tree cvs.cvshome.org ccvs module, you can
have a version of CVS with this feature.

However, Chris also provided a proof of concept set of shell scripts to
help you in the short term.

See http://lists.gnu.org/archive/html/bug-cvs/2004-06/msg00173.html
and http://lists.gnu.org/archive/html/bug-cvs/2004-06/txt5G0hQtIjfA.txt

If you hae already done other imports in your tree, you will need/want
to force a commit of the HEAD to be exactly the same as the previously
imported versions for now so that the stuff that works will all still be
visible. This will change the default branch from the vendor 1.1.1 to
the HEAD again. If you only have 1.1.1.1 versions from a single previous
import, you could just use 'cvs admin -b1' on those files instead of
forcing a checkin in preparation for a new cvs import.

        Enjoy!
