Yeah, after having them, I felt a bit naked not having all of those
'constants' defined.

Originally, all I had done was add --defaultno to the dialog command,
but Warren's patch makes a lot of sense, allow the user to 'try' the new
keymap before trying to do the rest of the install based on it.

This is definately something that I think is a good idea, but my focus
is on improving the usability and functionality of the installer in time
for 10.0. Unifying everything to the bsdconfig style is slightly lower
priority. Admittedly, the `bsdconfig networking` stuff is quite nice
