/dev needs at least the entries console and null, and tty1 for splash 
things (I think). You could create them like this:
mknod c 5 1 /dev/console
mknod c 1 3 /dev/null
mknod c 4 1 /dev/tty1

Or copy over your original /dev directory (without the stuff udev added) 
from the old system:
mount -o bind / /mnt
cp -a /mnt/dev /newroot/
