Would it be worth trying to collect some data on users running NetBSD on intel display hardware, to see if there are any cases where intel_drv works and modesetting_drv does not? As a datapoint, on a Thinkpad T480 runs OK with the default intel_dev. Renaming away /usr/X11R7/lib/modules/drivers/intel_drv.so and restarting X runs fine with modesetting_drv, and "grep Mesa /var/log/Xorg.0.log" gives
Both are equally bad for me. The console works perfectly but I get stuck in the blank screen heartbeat death with both (see kern/57268):(II) modeset(0): glamor X acceleration enabled on Mesa DRI Intel(R) UHD Graphics 620 (Kabylake GT2)

So fiddling with the default X driver for intel hardware is only part of the solution. We need to address the core issues in the i915kmsdrm that impact both.
