When kan we expect at update on the W83627EHF to include som fancontrol
and some of the other advanced fetures of the chip. I am sitting with a machine
suited with some nice 120 mm fans, but the minimum-setting on the fanspeed
is way to high, an it can not be altered in the BIOS.  

Unfortunatly i am lousy in C in general and i do not know anything about
kernel-development, so i cannot realy paticipate, in development. 
But maybe you can use mee as a  beta tester.
