Hello, everybody!

I've got an issue concerning IGD passthrough on calpella/sandybridge 
platform.
The IGD have passthrough-ed well on Win7 and WinXp until I setup native 
driver for GPU.

After installing drivers and rebooting domain the display got black when 
driver starts.

I found the similar issue

Could you provide any advice to make graphic works?


My system:
Hardware : EliteBook 8440p
Xen - xen-4.1.0-rc6
Linux 2.6.32.7
