Subject: Make serial console based installs actually work by:

1. Detecting the split /dev/ttyv0 / /dev/console case, e.g. you've
   booted with the -h flag and you have a VGA card also.

2. Adding an extra "menu" for selecting terminal type and adding ANSI
   to the list of compiled-in terms.

3. Opening the proper file descriptors before disowning ourselves.
