I gave a quick look at the motherboard, you are right (and I was wrong, 
sorry).While the w83791d is clearly visible on the Maximus/Rampage Formula
(http://www.overclock3d.net/gfx/articles/2007/10/31181936232l.jpg) this
is not the case for the MIIF.
Unfortunately it's not that easy to remove the heatsink and it makes the
warranty void, but I have found some images of the "naked" board. I
modified them to show you the well know chips, but I need your help to
identify those unknown chips that might be hwmon IC. This is the picture:

I suspect them to be the iROG marked chips as I think this board is the 
first Asus mounting such ICs and being capable of showing 
temperatures/voltages/fan speeds on an external LCD, included with the 
board. Again, unfortunately no other information is printed.

Both the BIOS and the Asus utility show the speed readings for every 
header but at this time I'm using only 3 fan headers (+ the CPU header). 
I'll give a try as soon as possible. However, as far as I know, no Asus 
utility can control this fans and other software only recognizes the 
winbond chip, but some regulations are still possibile in the BIOS. Is 
there a way to find out through a bus scan what chips are they? What can 
we do now? Should we try to contact Asus?

Thank you
Marco
