I agree with Mario. DKMS is gaining traction with Intrepid wherein it
will be used to distribute ATI and nVidia graphics drivers, e.g., they
are no longer packaged in LRM. I see no reason why the virtualbox
package couldn't do the same. In fact, you should do it for Hardy since
the ABI _will_ change again. -19.33 will be in -proposed by tomorrow. It
seems that each round of CVE updates also forces an ABI bump.
