On an OpenIndiana test image with the legacy stack as default, virtio_gpu bound a virtio-vga device through its package alias (console lost, Xorg drmSetMaster EBUSY), and the packaged /etc/X11/xorg.conf.d/20-virtio-gpu.conf forced modesetting on every machine.

virtio_gpu ships without aliases; /usr/share/drmadm/virtio-gpu.aliases lists them. drmadm select new binds them, select legacy removes them (fragment first, rollback, -R); drmadm status shows them.
The generic modesetting configuration is a template in /usr/share/drmadm/20-modesetting.conf. svc:/system/graphics/drm-perms (now also before the display managers) installs /etc/X11/xorg.conf.d/20-drmadm.conf only when the new stack is selected since this boot and removes its own copy otherwise; administrator files are left alone.
virtio-vga with the new stack selected still has no console (no console takeover in virtio_gpu); drmadm(8) and the README say to use virtio-gpu-pci.
G7 and R4 tests updated. Version 0.0.2.

Tests (hephaistos guests): G7 13 phases 114/0, R4 36/0, virtio-vga with packages installed and no selection 5/0 (vgatext console, no alias), package upgrade 5/0; host CI checks 11/0. Not run on the X230.
