I'm trying to run the app Wireless Tether. I don't know if the problem lies within CM7, Android 2.3.x, the kernels, or the app itself. I've been through so many ROMs and kernels in the last month that I'm absolutely confused with what worked when and under what circumstances. I get an error from the app, after it is granted su, it pops up with "unable to start tethering, is your device rooted?" and I've removed it from superuser and it requested to be added again, so the rooting problem isn't the case. EDIT: it doesn't work on a clean CM7 install, either. I'm about to give your ROM a whirl and see what happens.
