Ivybridge looks good.Here's my output.

$ bin/wflinfo -p gbm -a gl -V 3.1 --profile=core
Wflinfo: Creation of an OpenGL >= 3.1 context succeeded, but it
  had the wrong profile.  Fallback to requesting an OpenGL >= 3.2
  context, which is guaranteed to have the correct profile if
  context creation succeeds.
Waffle platform: gbm
Waffle api: gl
OpenGL vendor string: Intel Open Source Technology Center
OpenGL renderer string: Mesa DRI Intel(R) Ivybridge Mobile 
OpenGL version string: 3.3 (Core Profile) Mesa 10.2.0-devel (git-410d7ae)
OpenGL context flags: 0x0

$ bin/wflinfo -p gbm -a gl -V 3.1 --profile=compat
Wflinfo: Creation of an OpenGL >= 3.1 context succeeded, but it
  had the wrong profile.  Fallback to requesting an OpenGL >= 3.2
  context, which is guaranteed to have the correct profile if
  context creation succeeds.
Wflinfo error: Failed to create an OpenGL 3.1 or later context with requested profile

I'm looking at the code now trying to understand why NVidia fails.
