I found this document which describes how to read data from the sbRIO-9651's internal temperature sensors and I have tested out the example VI.
It it possible to access this data through the linux file sysem or somehow read it from a C program running in NI real-time?

jruhland,
LabVIEW is able to read the sbRIO's internal temperature through a component known as NI System Configuration API. It may be possible to call into this API in a C program. We're taking a look at the feasability of this now and will keep you updated with our progress.
Thanks,
Bryan

Sorry for the delay, I was looking into this in parallel. I confirmed the answer on Friday, but didn't get a chance to post.
The system configuration functions do have a C API. That API is documented here:

Thanks for the help, I abandoned my previous plan of creating a shared C library from a vi and used the SysCfg API instead.
I've attached the module's source as reference in case anyone else is interested in doing this in the future.
