Well, I'd just make it work with lm-sensors.  That way the snazzy 
controls are there.  The hard part (for me) would be figuring out how to 
tie the thing to the mobo.  I don't think most mobos have SPI / I2C / 
whatnot available as a header - so the only real option is USB.  A quick 
scan of lm-sensors maillists indicates it has generic support...  So a 
kernel driver compatible with hwmon would be the way to go.
