As a git user who has now done a number of CVS->git migrations over the
past few years, I also found that the various tools to do the
conversion do have their own issues (such as cvsps) which can lead to
incorrect history in some corner cases.  Unfortunately, in any big
repo with a lot of history, you do tend to find you trip up on them
in a few places.

My experience was that the CVS->SVN conversion tended to be rather
more reliable and accurate.  As a result, going GIT->SVN->git can
give a much better history.  At least in my experience.
