Okay - so you have a TFT panel.  That changes things.  
I assume you have a 1280x1024 panel.   What are the manufacturer recommended
timings for that panel (check the documentation).

Does this flicker?

okay - this is the interesting failure mode - please send me the log
file from this scenario.  We should be able to understand a 1280x1024
panel.  Make sure all the modelines are commented out, or this will
confuse the system.
