[Igor Lvovsky] Probably, I will go over the spec again.

[Igor Lvovsky] My patch fixes it for windows guest. I tried it for LID 
open/close events on my laptop. According to the spec OS should care these 
events through ACPI.
Now I have it works on windows guests via ACPI events, but on Linux guest it 
work without ACPI (weird).

[Igor Lvovsky] Not yet, but I'll inform you if I'll find something
