This appears to have either gone too far or not far enough, since the
current xenial of:

x86_64 x86_64 GNU/Linux

---------------
against the current virtualbox release (6.04). The -142 kernels didn't
have this problem.
Sidenote: my understanding is that the dkms modules haven't been
required by virtualbox in several years now. The 5.1.xx series is also
probably obsolete.
