servercat,
Hmm... Since you are booting with the rescue system on USB, it would be sda1. The install script (squeeze or wheezy) will need to write over the sda1 drive, so it is not possible :) sorry I forgot about that. There is a way to force rescue system stick to be assigned sdb1 but it's not foolproof, it's trial and error.
You could install uBoot only by running the script in http://projects.doozan.com/uboot/. And then put my rootfs or Davy's rootfs on a new USB, boot with that. But if you do that, you should set up netconsole immediately when you finish intalling uBoot, while you are still in rescue system.
My thinking is: if you reinstall uBoot, then the envs are reset to boot normal Debian system. That was the reason I'd suggested to rerun the installation so you can reinstall Debian also in one shot. But if you can't do that, then reinstall only uBoot is a good alternative. However, as I mentioned, you could get locked out if not being careful. So it depends how do you feel about doing that. If you get locked out, then you will need to install serial console to recover.
If this is not clear, please post back and I'll explain further.
