Userspace stuff doesn't ever go to dmesg.

All the print statements in sensors.txt are commented out.  I had to
uncomment them and rebuild the comp, then the program's output appeared
in the terminal i ran it from (either via halcmd loadusr or by hand at
the shell prompt).

The sensors backend needs to be configured for your system before it'll
emit anything very useful.
