I also have a machine with this same adapter. It's a Lenovo Thinkcentre 
"Tiny" machine. I believe the problem is that NetBSD's intel KMS code is 
not yet pulled up to the rev that supports Iris graphics.

That's the same as I get.

I had the same experience. I even tried disabling the framebuffer console 
which also didn't matter.

I don't think that there is a way to do it right this minute. If it helps, 
I've noticed that FreeBSD Beta 11 is supporting it. I think we'll just 
have to wait on the NetBSD side of things. It'll happen eventually.
