I don't think this is a regression. Probably, the new code is allowing a higher resolution. As the maximum bandwidth from the sensor to the USB bridge doesn't change, and a change from QVGA to VGA implies on 4x more pixels per frame, as consequence, the number of frames per second will likely reduce by a factor of 4x. I've asked the reporter to confirm what resolutions he is setting on 2.6.33 and on 2.6.34, just to double check if my thesis is correct.
