[meta-intel] [PATCH 0/2] [Dylan] meta-valleyisland: update README and machine conf file

Wed Mar 26 08:38:40 PDT 2014

Falk,

Well now, that's embarrassing. I had suggested i915 to Rebecca, but it
appears as though I was wrong and it was i965 that is needed. We'll get
this sorted - thank you for taking the time to post the details.
