I still get the looping: I press 'y', 'w', and am back to the 'do you want to detect...' question. /cdrom/pool/main/c/cdebconf-keystep/* has version 0.8.
On my first boot I did not get screen corruption, the question dialog was clean. On the second boot I did get the garbled screen again (see screenshot in comment 2), so this looks like a race condition.
