As a datapoint, the same W83782D on AMD756 (also I2C) works correctly with 
2.6.22:

w83782d-i2c-0-2d
Adapter: SMBus AMD756 adapter at 50e0

Jean Delvare recently worked on the ISA interface to these chips but it 
seems this would not be the cause if you are also using I2C. Our hardware 
appears rather identical...

I've attached (an excerpt of) my /etc/sensors.conf -- I once dug through the 
datasheets for those compute lines for example so perhaps its still useful 
even if 2.6.21 working for you probably means you don't have a config problem.
