YAY!!! That one seems to fix the issue.

Though I had to revert 7faa92339bbb1e6b9a80983b206642517327eb75 (well, I 
hacked check_horiz_timing_omap3 to always return 0). Otherwise I have 
"omapdss DISPC error: horizontal timing too tight" error when try to 
play anything above 320x240 or so. I'll look at the issue.
