I had a similar problem with X appearing to hang. In my case, I had to 
specify the full path:

$ grep kms /etc/rc.conf
kld_list="/boot/modules/i915kms.ko"

...in order to load the i915kms from the port graphics/drm-fbsd12.0-kmod 
rather than the one from the kernel. Yes, I had to build the port, not 
just install the pkg.

Caveat: Matt just upgraded to 13.0; I'm still on 12.2-RELEASE-p4 on 
account of sloth. I'm guessing Matt probably needs 
graphics/drm-fbsd13-kmod.
