No, I didn't rebuild graphics/gpu-firmware-intel-kmod, only
graphics/drm-66-kmod.

In the meantime I've opened an issue here:

https://github.com/freebsd/drm-kmod/issues/419

And as I commented there, the issue starts showing up for me with
freebsd-src commit 79b05e7f80eb482287c700f10da9084824199a05.

I will check if rebuilding graphics/gpu-firmware-intel-kmod makes any
difference.
