question on chroot patches

When we last deployed OpenSSH (v. 3.4p1), we used a chroot patch 
supplied by John Furman.  Does anyone know if that is still being 
maintained, and if so, where one may get it?  If not, do any of the 
other chroot patches use the same configuration syntax?

Specifically, it adds ChrootDir and ChrootUser to sshd_config.

Thanks,
