New patch works on 7.0 and 7.0-PRERELEASE, but currently hangs my
7.1-PRERELEASE just before activation of the single-user mode. I am
investigating -- I did the original patch for the syscons.c 1.453.2.1.
Changes in 1.453.2.2 look innocently, but 1.453.2.3 changed some
functionality, may be it is the culprit. Will inform on my findings.
