Well, I thing the second is outside the scope of the install system.
I have a new patch which should take care of both.

Perhaps smaller changes are enough.

Well, I believe it is a bug if the first part of the installation uses
one language, and the second part uses English. And I hope this bug
could be fixed before Woody is released.

Noted.
Here is a new patch for base-config. I moved the locale generation
from base-config and into termwrap where I think it belong.
The only thing dbootstrap need to do is to install the required
packages (debconf, locales, jfbterm, fonts?).
