Starting with a couple of leads posted on this list, I've put together a working driver for the vt8231. I've only been able to test it against my EPIA800 board, with the following output from 'sensors' under 2.8.7: vt8231-isa-6000 Adapter: ISA adapter VCore1: +3.47 V (min = -0.05 V, max = +4.42 V) +5V: +3.26 V (min = -0.08 V, max = +6.31 V) +12V: +12.56 V (min = -0.18 V, max = +15.00 V) fan1: 3971 RPM (min = 0 RPM, div = 2) fan2: 6425 RPM (min = 0 RPM, div = 2) ERROR: Can't get TEMP2 data! Proc Temp: +16.3 C (high = +276 C, hyst = -1 C) vid: +2.05 V I know this isn't quite right, but it matches the output from lm_sensors-2.8.7 under 2.4.27 (specifically the VCore as 3.3v not 5.v and the TEMP2 error). I'm not entirely confident in the ability to _input_ to the driver, that's next on my tasklist. In any case, the patch against kernel 2.6.8.1 is at: http://www.stanford.edu/~amarsh/vt8231/linux-2.6.8.1-vt8231.patch A patch against lm_sensors-2.8.7 is at: http://www.stanford.edu/~amarsh/vt8231/lm_sensors-2.8.7-vt8231.patch And a copy of my sensors.conf is at: http://www.stanford.edu/~amarsh/vt8231/sensors.conf One additional side note. I originally wrote the driver to use the VID sys file 'cpu0_vid' then rolled it back to use the current 'in0_ref.' I'd happily change back to cpu0_vid if that's the way the wind's blowing. I'm afraid I'm new to contributing to projects of this size. Please let me know what else I can do to get this driver in the mainstream.
