Following earlier explanation from uwe@ I have setup a build
environment for the additions. With a few minor patches, it works
every time. My NetBSD guests - mostly -current - now all run under
VirtualBox 6.1 with the corresponding additions.

Basically you need /usr/src and /usr/xsrc on the build host.
Display device can be either VBoxVGA, VBoxSVGA (they appear identical
within the guest) or VMSVGA (which used to have a problem with the
mouse not registering events, but now works just fine). VirtualBox
allows accelerated 3D to be selected only in VBoxVGA mode for NetBSD
systems, even if they say this combination has been removed from the
release; it still works for me.
