I ran into the same issue on a stable "lenny" installation made in june-july 2010.
I didn't use dpkg-reconfigure like the original reporter. I just did chmod g+w /var/spool/sa-exim/tuplets and that seemed to take care of the issue. Tuplets are now created (though I haven't yet verified that greylistclean will expire them). I assumed user nobody group Debian-exim with write for both user and group would be the right thing to have, since spamd would run as user Debian-exim and the /etc/cron.d/greylistclean is running as nobody.
