Bug#565790: cat /proc/acpi/ibm/video and must press power button

[Kamen Naydenov <pau4o@kagersoft.com>]

I can confirm this behaviour.
After command:
$ cat /proc/acpi/ibm/video
In gnome-terminal, tty1 and even in single mode I have same:
- black screen
- non working keyboard (even SysRq comands)

I have similar ThinkPad as original bug reporter:
$ dmesg | grep -i think

your ThinkPad

I'm with latest BIOS and EC

maybe  this is connected with video dirvers.
