Minor note about point 3 above: Unlike what I used for the above message, yesterday I used a netboot to install, and it would warn with a dialog if there was no bios_grub partition (because that option is apparently not supported in kickstart; but it works with preseed). Both were Ubuntu 12.04. My preseed was not created from the "ubuntu-server" default one, so maybe there is just an option in the "ubuntu-server" preseed that is not in my preseed that would suppress this useful warn dialog.
