I guess this is with net-snmp-5.9.4_2,1?

This script does not need to run as root. If you change snmpd.conf to:
extend cpu-temperature sh /root/x/snmp-cpu-temperature.sh
and set snmpd_sugid="YES" in rc.conf (to make snmpd drop privileges) and
restart snmpd, are you able to see the temperatures again?
