I've created a patch for the the lm_sensors w83781d driver that lets it
properly initialize and detect the chips in the Tyan dual-amd boards.  This
lets me get temperature monitoring without going into the bios first. 
Temperature and fan speed monitoring works, but voltage doesn't work correctly
for some inputs (like +12V) because Tyan used non-standard resistor values and
I don't know what they are.

I'm planning to give it to the lm sensors people soon.  In the past, they've
been very receptive to my fixes for the supermicro 370DE6 and vid settings for
socketA, P4, and P3-S boards.
