Woops.

In other words, we can guess there's no program to call to query and
text a password.

Have you tried having the boot loader pass the single-user parameter?
In a grub boot menu, you would hit e for edit and add "single" to the
"linux" line.
I'm not sure whether you'll be able to run dpkg at that point, but, if
so, you might be able to have a re-go at the PAM module. I'm not sure
that will be enough, either.
You may need to bring up the network interface first, of course, or
point dpkg to your install DVD.

Booting the DVD, dropping to rescue mode, and mounting the hard disk
would allow you a look at the logs to see what it was trying to do and
how far it got when you couldn't move ahead.
