Have you thought about using the dynamic sysctl tree stuff in FreeBSD instead
of having hw.sensors proc handler that walks the sensor tree?  You could just
give each sensor its own sysctl_ctx and tree.  You can then use standard
sysctl routines for handling individual sensor nodes, (or still use custom ones
with SYSCTL_ADD_PROC) etc.

OpenBSD doesn't support adding sysctls at runtime, so they had to use a
complex hw.sensors routine, but you can take advantage of the dynamic sysctl
tree in FreeBSD to reduce complexity.
