I found it is ported now. https://github.com/FreeBSDDesktop/kms-drm/commits/drm-v5.0 I tried it and it's somewhat working, thanks! However, I found two problems. 1. Console does not refresh automatically. When vboxvideo.ko is loaded, console stays black. Console preview looks fine, though. I found it's redrawn when the window is resized. Note I only tried it on a Windows host. I will try it with FreeBSD host soon but I think it'll be the same. 2. Console does not resize dynamically. Actually, it is not vboxvideo.ko's fault. It happens because vt(4) does not support monitor hotplug. https://www.virtualbox.org/wiki/Guest_resizing After I tried it out, I realized vboxvideo.ko is just a KMS driver and modesetting driver is used for X.org. IOW, we cannot resize X.org window dynamically when vboxvideo.ko is used. With vboxvideo.ko or vboxvideo_drv.so, 3D acceleration is still handled by the Chromium OpenGL pass-through stub. As always, it may be enabled with setting OPENGL option for emulators/virtualbox-ose-additions. BTW, Phoronix once reported 3D acceleration with VMware driver does not look good on VirtualBox anyway. :-p http://www.phoronix.com/vr.php?view=27348 Jung-uk Kim
