It looks like everything didn't get commited.  The sensors_vid.h file is
there, but the w83781d.c file is still at rev 1.90 and doesn't use the new

I have a patch for w83781d that will allow for proper initialization and
detection on the tyan dual athlon motherboards without entering the BIOS

It still requires init=0 to be specified, or the machine locks when the driver
is loaded.  I looked at every reference to "init" in the w83781d.c and the
code it triggers, and I can't see any reason for the lockup.  Do you know if
there is any code init triggers that I wouldn't find this way?  There
shouldn't be any reason the temperature/voltage limits can't be initialized
with this board.
