Maximum room temperature (Tyan S246x)

Temperature monitoring for the dual processor Tyan board is mostly
working in lm_sensors 2.6.3 (March 22, 2002).  See the tickets
referenced on the lm_sensors web page:   http://www.netroedge.com/~lm78/

Unfortunately, you still have to go into bios on every boot to
initialize the monitoring chips, but everything seems to work. 
Fortunately it seems progress is being made - a solution was posted on
April 11th (again, see the web page).

Good luck,
Vann
