Er, apologies for the confused bug entry. The installer found the yaboot partition with the ext3 filesystem label, and added it to the fstab. The boot sequence was interrupted because of the bogus fstab entry, and that explains the root prompt (which of course I could exit out of easily and find myself in a functioning system).
