Well if you're already familiar and happy with grub installed on your 
linux system why not install grub from ports and continue to use it. 
Install it into 6.3 before you replace linux with 7.0 and add extra 
commands to menu.lst ready to boot 7.0 from da1. Then when you install 
7.0 just tell sysinstall not to install a boot manager.
