Works for me. Please give a complete recipe starting from emacs -Q.
Mine:

mkdir /tmp/cvsroot
export CVSROOT=/tmp/cvsroot/
cvs init
mkdir /tmp/foo
cd /tmp/foo
touch file
cvs import -m "import" foo VENDOR RELEASE
cd ../
rm -rf foo
cvs co foo
cd foo
emacs -Q file 

make some changes to file, save, C-x v v, file checks in fine.
Press C-x v v again, "Fileset is up-to-date", as expected.
