There's no default value, most likely, and according to man page, the
default_mode one is only used with KMS video driver, are you using one?
Looking at the older drm code that is still in tree
(sys/dev/drm2/drm_fb_helper.c), all it does is reading per-output
setting, and if none, using the default_mode one. Most likely the newer
in ports does the same; I didn't check and don't have access to anything
using drm drivers at the moment.
