Clemens,
The company we got he board from has become increasingly unhelpful, so I figured I'd contact the U-boot people since you are 1) bound to be more helpful, 2) have to be faster than a 1 week turn around time and 3) actually created this particular technology.
Thank you for your advice. I finally have the datasheet for the LCD screen, so I'll be modifiying the configuration for a little while. So it looks like a clocking issue. That seems resonable.
As far as that notice goes... I didn't intentionally put that there, it must be my company trying to dodge any inferred responsibilty in this email, I'll try and remove it if I can.

Hi, Roger!

Right... The arcitecture is arm, the module is a PXA270. The odd bit
about
this whole mess is that the 'board' is actually a business-card sized
board
which we plug into our main-board. That is a CCXP270 by Digi International.
Did you contact them already?
They shipped us the development environment which included some version of U-boot vintage 2005. Since this is almost certainly an out-of-date version of U-boot, should I update my Uboot to the most
recent
version?
Generally yes. But that doesn't necessarily mean that this will solve your current problem.
I've run into an issue with my uboot, I want to display a bitmapimage when the system boots; however, all the screen does at startup is fade from white to black and back until the OS boots up.
The TFT Displays I've seen fade slowly their colors and settle with some line or block artefacts or flash when they are not clocked properly. If you let them that way for some time (several hours) the liquid crystal stuff gets polarized (or whatever effect that is) and the stripes will stay forever. Check that the clocking fits to the datasheet.
