This bug is still happening on Oneiric, however, removing the Nvidia drivers will fix this issue. I tried all versions of the drivers. I even installed the one from their website (version 295.33) and still not luck.
fyi, I tried the extracted isight.fw I tried creating a udev rule I tried to recompile uvcvideo The only thing that works is removing the NVIDIA drivers.
