Hi Mark, I'm sorry, I have no experience getting SASL to work with pam. But I remember having read some things about pam in the Cyrus SASL documentation pages (included with the distribution I think). So I suppose it should work. Maybe someone else on the (correct) subversion users list can help you?

Personally, I alerady use pam_ldap for auth on my server (which also helps support svn+ssh for those that don't use keys).
