Root Problems w/tethering and 2.2

[dfine06]

Ok so heres the deal. Ever since i loaded 2.2 i havent been able to tether anymore. i tried everything. reinstalling access control etc. in the show log im getting the "enabling access control error" but everything else is fine. anyone else have this problem. im also running the kernal that was posted in Fab's post if that has anything to do with it. I need to get this working again.
