I would be very excited to see a working camera driver.  I made a false 
start trying to bring the camera changes from beagleboard/hw-validation 
kernel to 3.4, but I am not very good at git and gave up quickly.  If we 
got a newer kernel with the same 'not-quite-working' driver that is in 
the hw-validation kernel, I would spend some time tweaking command 
sequences to see if I could get it working.
