relativization

[Paul Kroeger]

One of the most frequently cited tests for subjecthood in AN
languages is relativization, based on the Keenan and Comrie
accessibility hierarchy.  Can anyone give me examples of languages
which are neither Austronesian  nor ergative in which only subjects
can be relativized?  (The non-ergative restriction is to avoid
getting entangled in the issue of what counts as the subject in
languages like Dyirbal and Mayan.)  Many thanks,

Paul Kroeger
