Thanks... my response time might be inversely proportional to the amount
of blood in my caffeine. ;-)

Check HSYNC, VSYNC and the Pixel CLK and the supply voltages if they are
within the spec. (i.e. on the small standard TTL display interfaces)
If the display controller has also a working driver on Linux' side, you
should be able to figure out the right timing parameters for your display,
too (embedded in some timing tables). Transfer that to U-Boot and see what
happens.

Okay, some people propably won't help you if they care about this legal
