Attached is a simplified ipmi-fru that you can hopefully use to extract the FRU information you seek. "gcc ipmi-fru-example.c -lfreeipmi" is all you need to do. I took out a lot of stuff, and there a number of special cases not handled. It may not work for all motherboards, but is a good place to start. As for sensors, I figured you would probably want to use libipmimonitoring, since it's at a much higher level. I would suggest looking at the ipmimonitoring-sensors.c file. Hopefully that's enough to get you going. LMK if you need some help deciphering the code more.
