Hi Nathan,

If I had any documentation specific to the 1550, I probably
wouldn't ask the list. :) I'm pretty sure I just ran
sensors-detect with a kernel having i2c and lm-sensors
modules installed.  The best I can offer is my sensors.conf,
appended to this message, though I make no assertions that
using it is a good idea.  Also at the bottom is sample
output from "sensors" for comparison.

At the time OMSA and Debian didn't get along.  It seems that
might be better now, and would probably be worth trying if
starting from scratch.

thanks; now that it hit zero and still works, it better not
be the power supply. ;)
