We are supposed to be compatible with ePAPR spec of the device tree (so is Linux), so no special handling is needed.

Regarding the error it might be caused by the recent import of changes for ARM which affected FDT infrastructure code (http://svn.freebsd.org/changeset/base/239268). We had a side conversation with Marcel regarding DSI panic during localbus node processing, which seems similar to what you're seeing. Can you try some older code base (prior to r239268) to see if it shows the same/related problem?
