Ok, while looking for a solution to my problem I found that ticket #1148 matched it, I have a S2466N-4M (the difference between this board and the S2466 is that it has a 4MB rom rather than 2MB) the modprobe w83781d force_subclients=0,0x2c,0x4a,0x4b trick from ticket #941 isn't working on this, dmesg outputs: i2c-proc.o version 2.6.1 (20010825) w83781d.o version 2.6.5 (20020915) i2c-core.o: driver W83781D sensor driver registered. i2c-core.o: client [W83627HF chip] registered to adapter [SMBus AMD768 adapter at 80e0](pos. 0). i2c-core.o: client [W83627HF subclient] registered to adapter [SMBus AMD768 adapter at 80e0](pos. 1). i2c-core.o: client [W83627HF subclient] registered to adapter [SMBus AMD768 adapter at 80e0](pos. 2). i2c-core.o: client [W83782D chip] registered to adapter [SMBus AMD768 adapter at 80e0](pos. 3). w83781d.o: Subclient 0 registration at address 0x49 failed. i2c-core.o: client [W83782D chip] unregistered. This is kernel 2.4.20, could it be the oldish i2c version?
