Needed i915.nuclear_pageflip=1. Didn't even know we had such a knob.
Anywyas, all it tells me is
"Running test on pipe A with resolution 1920x1080 and sprite size 1920x1080 alpha 1"
and similar lines, and mostly I just see a black screen or a blinking backlight.
So I can't tell what it's actually doing.
