Detect missing kernel modules on startup

This sort of thing can be resolved by switching the package over to use DKMS instead.

That hopefully prevents this error from happening (the packages from the virtualbox website seem to have this implemented already, but in ubuntu it is still a no go....). But even then, if it happens, it should be detected directly.

Here's the particulars that enable DKMS support. They're also rolled up into the FFe bug for the new version (LP: #268795)

I'm not attaching the build log and install log to this bug, see bug 268795 for this information.

This bug was fixed in the package virtualbox-ose - 2.0.2-dfsg-0ubuntu1
