who is this ?

The SFR at 0x7c has an offset register configuration bit (bit 4) that could 
effect which voltage the offset applies.  That feature has not been 
implemented yet.

The CONF register at 0x7f has a fan spin up reduction mode that has been 
implemented in some of my other drivers or on other chips in this driver, but 
not implemented yet.

Adding the D102 should be simple.

:v)
