Try the printascii hack[1] to see what's going on.
(if you can't get this to work you'll need to fix this probably before
anything else)
Common problems are that rootfs can't be mounted,
init can't be found or something like that.
It might also help if you can get framebuffer running,
- maybe you can think of another possibility to debug?
If you've got working redboot images available
(see my redbootbuilder scripts [2] if not)
this might be also worth a try.

Try with 57600 Baud first, you can always do faster later on.
