Thanks for the hint - I think that it should be fairly easy to fix (I 
temporarily force debugger output to the serial port when working on the 
video routines). I'm quite tempted to make this a permanent behaviour 
when CONFIG_DEBUG_VIDEO_CONSOLE is enabled, and change the default to 
"false" so that this becomes a developer option.
