So on the box that has these issues, funny enough /etc/fbtab never gets
honored and so /dev/drm0 stayes owned by root. When I chown to me, it's
apparently not trying to use shm anymore because I stop seeing these
crashes. I think they come back, but it could just be that I reboot at
times and I'm not paying attention to these details.
I haven't yet understood exactly why login_fbtab() isn't happening.
It's called from xenodm and seems to work on some machines. So there's that.
There are two places where login_fbtab is called in xenodm and one of them
has this note: /* XXX not working because of pledge() */
