Just to clear this up!!
Since know one seem to be sure about the tethering thing I asked dragonzkiller and he said
"not if you did the tethering hack. but the tether hack must be done before flashing CM7 and every time after an SBF"
Right after he replied to my tweet he tweeted
"IF (BIG IF) i get time this week, I'll release the version of #cm9dx2 i had running in the video. yes it's old, but it's all i have."
Edit: I jumped the gun a bit here!!!!
The tether hack IS NOT
the patch found in this thread Dragonkiller told me it's the one found on the Droid3
Dragonkiller: "@CarlosBattousai no. It's the one that was found on the DROID3, but it works for us too."
Hopefully all the tetehering questions have been answered now!!!
