My understanding is that gen9 intel chipsets get modesetting, gen8 and
earlier still use xorg-x11-drv-intel. (For f24+)

That's a fedora specific patch I haven't seen yet. But given that's
what we want to move to its ok anyways.

Oddly, I have a skylake laptop here (gen 9) and it does indeed use
modesetting driver, but I only get DRI2 (which is why I haven't seen
any DRI3 problems I guess).

Is DRI3 only default for xorg-x11-drv-intel ?
No. This line does not tell you much.
Easy way to check for DRi3 is to run "glxinfo|grep buffer_age" ... if
you have to lines in that output you'd have DRI3.
As for why you haven't seen problems ... because usually it "just
works" (even better than DRI2).
