I would suspect bad SDRs. The entity information is wrong, at least, I
suspect other things are wrong. The errors are also not valid error
values, so this is very strange. The "1" in the top 8 bits

I suspect that the sensors say in their SDRs that they don't have
working thresholds, so OpenIPMI won't let you set them.

That's a good FAQ; I'll add the following to the FAQs.
The top 8 bits of an error are the error type (basically where the error
came from). The rest of the value is the error itself; make sure to use
the proper IPMI_xxx_ERR_VAL() to extract it. The error types are:
* 00 - An OS error or an error from OpenIPMI itself. These are
standard errno values and can be decoded with strerror() and friends.
* 01 - An error from the remote management controller (An IPMI
error). You can look these up in the IPMI manual.
* 02 - RMCP+ error. These are in the IPMI LAN section of the IPMI
manual.
* 03 - SoL (Serial Over LAN) errors. These are in the SoL section
of the IPMI manual.
You can convert any of these errors to a human-readable (currently
English only) string using ipmi_err_get_string(). See
include/OpenIPMI/ipmi_err.h for more details on these things.
