I'm certainly not going to try to talk you out of it, this does need to be 
done as eventually It would be nice to merge these changes into the main 
distro.

Exactly right, I followed Zach's lead on this, as putting u-boot into high 
memory and having memory at 0 seems to be somewhat standard for some reason.
To be honest I have no idea if this is really required or if it will break 
anything, but I was trying to code quickly so I opted not to take the road 
less traveled.

I'm actually experimenting with several toolchains, but the most stable for me 
seems to be Gregs old pre-build one.
You can get this directly off the uclinux website, but it appears to be down 
at the moment.
We've also got it on our SoM ftp in the tools directory.

This is a very valid Coldfire topic, so I don't really want to do this off 
list, but since your not really talking about using u-boot, you probably 
should move over to wildrice, you'll probably find more support in this area 
there.

(I know it looks a little clunky, but trust me it's very active)
