I was having trouble with wireless after various tests I jacked it up. I tried your compiled version and dumped the tar and image file from 1/7 in there and wireless tether worked to turn on and off. When I turned it back on it rebooted. On previous build it would reboot when I turned it off. Could be worse I guess. The wireless tether for android is tons faster than winmo for me.
