Found out this morning that this bochs-drm would be used when running a Xen HVM
with VGA/Xen graphics (probably also KVM when setting VGA). The effect of
blacklisting bochs-drm will be that those VMs will be falling back to use the
EFI VGA framebuffer (as before). Which looks more or less the same for just a
server install. It will lack to be supported by a DRM driver wrt Unity. But at
least it cannot be seen as a regression.
