Joe,

please have a look at http://www.xilinx.com/ml410-p. The pages do 
contain information, documentation, and examples on how to use U-Boot 
and Linux 2.4 on the ML410.
There are Linux 2.6 solutions for the ML40x boards (ML403 and ML405) 
from MontaVista and Wind River. Since the ML40x boards are in key parts 
identical to the ML410 you can use those ports as a starting point for a 
port to the ML410.
