That's easy.
1) create a project at github or any other git hoster and a plain git
repository in this project.
2) create a local git repo with 'git init', use git-cvsimport to
import the cvs repo into this git repo.
3) add the git hoster (i.e. github) as a remote in your git repo via
'git remote add' (or just copy'n'paste this from the hosters
description).
4) push the imported cvs repo, which is now your git repo, to the remote.

You can use git-cvsexportcommit to get it back into CVS.
You can also use git-cvsimport to get your git-repo up-to-date,
because I don't think there is a way that github itself can keep track
of an external CVS repo.

Hope this helps -- looking forward to the shiny new git-completion!
