I recommend installing a newer u-boot, which will remove the need for a 
"nand erase rootfs" before flashing a new image and which will also have 
the default console on USB. There is of course a theoretical risk of 
bricking your device if you do not have a debug board, so proceed at 
your own risk.

The most recent u-boot image from 
is probably OK, but you may want to ask other people for confirmation.

You would also need to edit your u-boot environment (specifically the 
"stdin", "stdout", and "stderr" variables) to get the console onto USB. 
There is an "openmoko/trunk/src/host/envedit/" utility which might be 
usable but I have never tried it (and its README only mentions GTA02).
