Thanks for your help. :-)
8tw, I think hiding kernel messages with the welcome screen is a bad idea. I wish i could work with the boot loader just like what you can do with grub and lilo.
Try looking in the Hardware index for a level shifter circuit.

You can, u-boot is script-able, you need a serial port connection first (the same serial port is used by u-boot as is later used by /dev/console).

Keep in mind that changing the U-Boot scripting might send you back to the store for an eJTAG unit.
