I got two Asus boards here (TX97-E and A7V133-C). If the pins are
unadvertised, how will I know where to find them? Anyway I chose the
software path for now... although it doesn't work.

Still I don't have the more simple electronics tools to do that, poor
me.

There is a beautiful schematic on the CD. You can't blame AD, their kit
is excellent. Had I read it before posting, I wouldn't have to ask Sean
about it (although my knowledge isn't sufficent to refuse
confirmations).

You're right, i2c-pport is obviously what I need. I tweaked the values
there to match what I read on the schematic. I think I have everything
OK, but I can't get it to work for some reason. See my reply to Sean for
details.
