# DF-5198 — live-path exercise of fire_saver (the set_video_mode twin of
# DF-5114/DF-5197). Run as root on the DragonFly guest (vm.sh run_root).
# Exercises: module load gate (get_mode_info), blank dispatch, ~13s of fire
# rendering across two cycles, unblank restore, module unload.
# Success criterion on stock kernel: all markers printed, guest stays up,
# no panic on the serial console. The latent OOB branch itself cannot fire.
