This happens all time for me with virtualbox-kmod as well in current.
Changes to src breaks certain (kmod) ports and there's always a delay
until they are fixed. This is life in -CURRENT. I accept this and don't
go bitching to virtualbox-kmod maintainers about it. Your usage is an
edge case so naturally there will be a longer delay before breakage is
noticed, until we can get automated CI up and running (even so, there
will be a delay).

With graphics, there's a software fallback (vesa/scfb), virtualbox has
no such option.

For stable usage, there are -RELEASE options.
