Because sensors-detect will find it...  also, there is something useful
hooked to the w83627dhg, in GP31.  I wanted to document that.  I didn't
check whether the w83627ehf driver exports the gpio pins or not.

I don't know what are the safe VTT limits for the processors supported on
this board.  The board supports every LGA1366 processor (Core i7, Xeons
3500,3600,5500 and 5600 sequences, although the 3600/5600 and latest i7 are
only supported on rev 2.0 of the board (which I don't have).

I am leaving it untouched for now, as well.
