Maybe you can try testing newer Intel driver, that seems just a few days from including in OI hipster.
There's also text install ISO/usb (20160421 is latest from http://dlc.openindiana.org/isos/hipster/)
I suppose you are updated to latest /hipster (pkg publisher to see, pkg update -v)
How to test per-package repository: (use beadm create to make a Boot environment copy)
search for xorg-video-intel on http://buildzone.oi-build.r61.net:1000/ userland
(will be refreshed, it's alp's repo for testing)
There's always someone on #openindiana Freenode.net IRC and openindiana-discuss Mailing list
