I compiled a new version of the boot.bin file provided by Atmel and it boots 
the old version of uboot (0.3.2) with no problems. i.e. I don't need to play 
with the "boot mode select link" to make it work like I do with uboot-1.1.1. 
There must be some changes between uboot-0.3.2 and uboot-1.1.1 that have caused 
this problem.

output:
<press reset>

boot 1.0 (Aug  2 2004 - 12:12:24)

Uncompressing image... done!

starting application

U-Boot 0.3.2 (Jun 24 2003 - 17:04:08)
