 the method used to copy the data to the SDcard placed the data in the
wrong place.

 code execution begins (if the S3C6410 is the same as the S5PC100)
from loading the data 0x34000 bytes from the END of the SD card.  by
placing u-boot at exactly this location, guess what happens?

 if the two partitions at the front were not EXACTLY the right size
(which is difficult to do) then when copying that data onto the end
partition, u-boot would have been placed in entirely the wrong place.

 resulting in arbitrary code execution, hence the lovely pretty
patterns on-screen.
