Bug#689268: Intel HD 4000 (Ivy Bridge) graphics freeze

[Ingo <ingo.steiner@gmx.net>]

With 256MB of RAM assigned to graphics all is 100% stable here since
over 2 weeks. Also 512MB seem to be no problem, just if I enable
"Maximum DVMT".

I checked with the specifications of my MoBo (Intel DH77EB) and it says:

 Dynamic Video Memory Technology (DVMT) 5.0 support
 Support of up to 1.7 GB Video Memory with 4 GB and above system memory
configuration

So these 1.7GB probably exceeds what the driver (or PAT) is capable?
