openvt -s -w is probably better than chvt. It could be used to create a
new vt where the rescue shell will run, and once the shell is exited
(no need to change what the rescue info says) gets back to the original
(g-i) console. This could even be used with text backed d-i.

Having a console widget in the gtk frontend would be neat.
