I can't quite follow why you need rescue mode. After the
login/password ( Xorg not running) in your sequence above,
just don't run startx. Then edit the sources list, adding non-free to
it. Now run apt or apt-get to update, and install the package.
$ sudo apt-get update
$ sudo apt-get install firmware-amd-graphics
I've attached my sources.list as a pattern, though you can leave out
the lines starting with deb-src.
