Thanks a lot for the link. Believe it or not, now I can resume from a console 
screen at least. That is a great advantage already. With the video_post 
script that was posted on the above link, it does come back up. Of course 
issues remain, as Ethernet is flaky, sometimes comes back, sometimes not, 
etc, but it is already a great step forward. 

However, I would still like to know, if it can be done with no usage of such 
3rd party tools. Is it entirely impossible?
