Hi,
I found this thread when googling for sun blade 100 sensors.
I applied your suggestions on Corentin's patch, and it works great
on my Sun Blade 100 too, with kernel 3.1.1:
% sensors
adm1023-i2c-0-18
Adapter: SMBus ALI1535 adapter at 1fe02000600
temp1: +28.0 C (low = -55.0 C, high = +127.0 C)
temp2: +59.0 C (low = -55.0 C, high = +127.0 C)
Hopefully the patch can make its way into a future kernel
so I don't need to maintain it next time I upgrade.
Thanks,
