Alright, hoping this stuff can be helpful.
Here we have the Wildfire S cm9 dev post. http://xdaforums.com/showthread.php?p=25618969
The dev modpunk says there's no bugs except camera and HQ videos. So that means they've fixed Wi-Fi and USB tethering. Here's the source page, hope it can help. http://git.cryptomilk.org/

Tethering isn't a big issue
We can use third party apps like open garden for wifi tethering and easy tether for USB tethering
Let the devs concentrate on more important things and life
