for me, this was quite straightforward on a 405 board. you should 
remeber to create two device nodes in your filesystem, though:

crw-rw----  1 root root 5, 1 2005-04-04 04:03 console
crw-rw-rw-  1 root root 1, 3 2005-02-20 11:39 null

else it won't work...

one thing to note is that udev is quite slow on bootup (at least here). 
after init is started some initial device nodes are created, this takes 
like 5 to 10 seconds here. i don't know if there is a way to decrease 
that time:

Freeing unused kernel memory: 92k init
INIT: version 2.86 booting
Mounting a tmpfs over /dev...done.
Creating initial device nodes...done.

that is a bit annoying... but i didn't put any energy in resolving that 
issue yet, so maybe it's easy ;)
