possible fix

Try this patch. I think probably just clearing the truncate bit should do it, but if that doesn't work uncomment this line:
//lvtma_bit_depth_control &= ~AVIVO_LVTMA_BIT_DEPTH_CONTROL_SPATIAL_DITHER_EN;
and try again. As for testing, all you need to do is copy the new files over and stop and start X:
sudo /etc/init.d/gdm stop
sudo /etc/init.d/gdm start
